NTSB Factual Report

HISTORY OF FLIGHT

On July 7, 2016, at 2042 mountain daylight time (MDT), Delta Air Lines flight 2845, an Airbus A320, N333NW, landed on runway 13 at Ellsworth Air Force Base, Rapid City, South Dakota (RCA). The airplane was not damaged and there were no injuries. The flight was a regularly scheduled passenger flight from the Minneapolis St. Paul International Airport, Minneapolis, Minnesota (MSP) operating under the provisions of 14 Code of Federal Regulations Part 121, with a planned destination of Rapid City Regional Airport (RAP).

The flight crew reported the takeoff, climb, cruise, and initial decent to be routine until nearing the Rapid City area. The captain was the pilot flying and the first officer (FO) was the pilot monitoring for the flight leg.

Prior to arrival into the RAP area, the captain anticipated and briefed the ILS32 approach; however, due to his personal procedure, he also briefed the RNAV/GPS14 approach. Prior to contacting Ellsworth Approach Control, the FO obtained the latest weather for RAP, which included wind from 140 degrees at 4 knots. The approach briefing included the airport information page, the anticipated taxi route to the gate after landing, and the close proximity of RCA to RAP.

At 2029:29, the airplane was descending through flight level 235 (about 23,500 feet above sea level) descending to 17,000 feet, and the flight crew made initial contact with Ellsworth Radar Approach Control (EA) The approach controller acknowledged and cleared the flight to descend to 5,300 feet and to expect a visual approach to runway 14. The crew acknowledged, and discussed the need to descend more rapidly. The captain was demonstrating to the FO a technique on setting up the Flight Management System (FMS) to configure for approach. During this exchange the airplane was approximately 45 nautical miles east of RAP.

At 2034:58, the airplane was abeam RAP and the EA controller instructed the crew to fly heading of 300 degrees for a downwind leg to the visual approach. The EA controller and the RAP tower controller discussed on landline communications that the airplane was high and fast for the visual approach. During the exchange the airplane descended through about 12,000 feet. Field elevation of RAP was 3,200 feet and with a nominal remaining flying distance of about 15 to 18 miles the airplane was positioned well above the typical 300 feet per mile descent.

At 2035:18 the captain noted that the airplane's speed was too high, and then noted that his technique on the FMS was not going to work the way he intended, and switched back to open descent. At 2036:30 the captain said "there's the airport," and called for gear down and flaps one. At this point the airplane was east of RCA, and RAP was south-southwest of the airplane.

At 2037:15 the EA controller instructed the flight to turn to a heading of 230 degrees, for the base leg of the visual approach. At this time, the airplane was descending through 9,200 feet and was positioned 9 miles north of RAP. Total flying distance via base leg and final would have been about 12 miles. Ellsworth AFB was directly abeam the left side of the airplane by about 4 miles.

The FO advised the controller that they were "a little high" and requested an extended downwind leg. The controller approved and asked the pilot to advise when they were ready to turn in. The airplane had turned about 15 degrees left during the previous discussion, and continued to slow. The airplane had travelled about 5 miles in a northwesterly direction, and was descending through 6,600 feet, about 11 miles north of RAP when the controller asked the pilot if he could begin a turn toward the runway. At 2039:12 the pilot advised he could accept a turn and that he had the field in sight. At that time the airplane was 12 miles north of KRAP, and less than 2 miles abeam the extended centerline. KRCA was directly between the airplane's position and KRAP about 6 miles south. The EA controller advised the pilot "cleared visual approach runway one-four. Use caution for Ellsworth Air Force Base located six miles northwest of Rapid City Regional." The FO acknowledged the approach clearance, and said to the captain "you got the right one in sight?" The captain replied "I hope I do."

After turning onto the base leg the captain selected a direct radial to the ZUDIM intersection, the final approach fix for the RAP RNAV GPS 14 approach, and armed the approach. ZUDIM is located 1.2 miles southwest of RCA. The captain reported that the airplane captured the approach about 5 miles from ZUDIM. The FO reported that he observed his navigation display (ND) and the flight was straight on the "correct" navigation line to the runway.

The airplane turned left, passing through and slightly west of the extended centerline for RAP runway 14. From 2039:45 to 2040:45 the airplanes descent rate slowed and was close to level at 4,900 feet. This altitude and position is consistent with the altitudes published on the RNAV 14 approach chart in that area; the specified altitude for crossing ZUDIM waypoint, directly abeam RCA, is 4,900 feet.

During this period, at 2040:10, the pilot asked if he should contact tower, and the EA controller instructed him to switch to the tower frequency. At that time, the airplane was about 5 miles north of RCA, about 11 miles north of RAP and positioned close to the extended centerlines of either runway. The captain switched off the autopilot, and directed the first officer to clear the flight director display. Just after switching to the tower frequency, the airplane began a rapid descent from 4,600 feet, about 3 miles from the RCA runway threshold, to landing at KRCA, with a field elevation of 3,276 msl.

The captain reported that about 500 feet agl he did not observe the PAPI lights; however, he remained "focused on the visual approach." At 2041:25 the captain stated "confirmed stable." The airplane was 1.5 nm from the threshold of KRCA, 8 nm from KRAP. The airplane was descending approximately 1,200 feet per minute, and the captain said "this is the most [expletive] approach I've made in a while."

As they approached the runway, the captain retarded the thrust levers to idle, at which point they realized that they were landing at RCA. According to both crewmembers. the landing runway 13 was "uneventful" and they cleared the runway onto taxiway "D" and notified the RAP air traffic control tower.

At 2042:24, the RAP tower controller notified the EA controller that DAL2845 had landed at RCA instead of RAP. The EA controller contacted RCA tower and began the process of handling the "wrong airport" landing with the tower and airfield operations personnel. On the ATC interphone, the RAP tower controller stated that he was initially watching the airplane on the tower radar display, but at the time of landing was entering traffic count information.

AIRCRAFT INFORMATION

N333NW, manufacturer construction number 0329, was an Airbus 320-211, manufactured in 1992. The airplane had a maximum ramp weight of 170,635 pounds, and had a total passenger seating capacity of 160, and contained 4 flight crew seats and 5 cabin crew seats. Recorded data and airline records indicated no relevant mechanical, systems, or maintenance issues with the airplane.

Electronic Flight Instrument System (EFIS)

The incident airplane was equipped with an electronic flight instrumentation system. The system included 6 flat panel displays, of which 2 were considered the Primary Flight Displays (PFD) and 2 were considered Navigation Displays (ND), which provided flight and navigation information in a digital format. The crew reported they operated the ND in Rose NAV mode which displays a full compass rose oriented to the aircraft heading, a depiction of the aircraft position with reference to the flight plan inserted into the FMS, and additional information associated with the flight plan. The destination runway and the runway identifier are depicted in white. In some cases, parallel or crossing runways are also depicted. According to Delta documentation the ROSE NAV mode "is particularly useful for maintaining orientation when being vectored near an airport prior to approach…"

METEOROLOGICAL INFORMATION

The Rapid City Regional Airport weather observation at 20:58 indicated clear skies, 10 miles visibility and light winds from 170 degrees.

Sunset was at 20:38, approximately 4 minutes prior to the event, the end of civil twilight was 21:13. According to NTSB Meteorological staff, the sun would have been at an azimuth of about 304 degrees true and about 1 degree below the horizon at the time of the incident.

AERODROME INFORMATION

Rapid City Regional Airport (RAP)

Rapid City Regional Airport was located 8 miles southeast of Rapid City, South Dakota, had a field elevation of 3,204 feet msl, and was located at a latitude/longitude of N44°02.7'/W103°03.4'. The airport was serviced by an FAA Air Traffic Control Tower that was in operation from 0600 to 2200 local time. The tower was in operation at the time of the incident. Radar services to DAL2845 were provided by Ellsworth Approach Control, located at the Ellsworth Air Force Base. RAP runway 14/32 was 8,701 feet long and 150 feet wide, the surface was concrete and grooved. Runway 14 was equipped with high intensity runway lights (HIRL) and runway end identifier lights (REIL). Runways 14 and 32 were equipped with a 4-light precision approach path indicator (PAPI) on the left side of the runway with a 3.00-degree glide path angle.

Runway 14 was serviced by an RNAV and a VOR approach.

Ellsworth Air Force Base (RCA)

Ellsworth Air Force Base was located 5 miles northeast of Rapid City, South Dakota, had a field elevation of 3,276 feet msl, and was located at a latitude/longitude of N44°08.7'/W103°06.2'. The airport was serviced by a US Air Force Air Traffic Control Tower that was in operation on the day of the incident from 0800 to 2100 local time. The airport was also equipped with a military airport beacon, which operated from sunset to sunrise. RCA had a single runway designated as 13/31. Runway 13/31 was 13,497 feet long and 300 feet wide, the surface was concrete and grooved. Both runways had a 4-light PAPI located on the left side of the runway with a 3.00-degree glide path angle, HIRL, Approach Light System with Sequenced Flashing Lights (ALSF-1), and REIL.

Each runway was served by an ILS approach.

Delta Air Lines' Operational Specific 10-7 and 10-7a Pages

Delta Air Lines provided Delta pilots with operational specific information on airports that are served by Delta Air Lines. The information is provided as a 10-7 page, also known at Delta as the "green page," within the Jeppesen Chart structure. The information provided by the 10-7 charts includes operation frequency, gate number information at the specific airport, airport specific procedures for departures and arrivals, general information, and Special Notes. The 10-7 page for KRAP provided within the special notes section the following information: "Ellsworth AFB lies northwest of RAP on final approach for runway 14. These airports have similar runway alignment and can be mistaken for one another."

FLIGHT RECORDERS

The cockpit voice recorder (CVR), an Allied Signal 980-6022-001, serial number 0777 was a solid-state CVR that recorded 2 hours of digital cockpit audio. The recorder was received with no heat or structural damage and the audio information was extracted from the recorder normally, without difficulty. The quality of the audio was characterized as good to excellent. A CVR group was convened and created a transcript. Timing on the transcript was established by correlating the CVR events to common events on the flight data recorder (FDR).

The FDR, a Honeywell SSFDR, Model 980-4700 serial number 4425 records a minimum of 25 hours of airplane flight information in a digital format using solid-state flash memory as the recording medium. The recorder was received in good condition and the data were extracted normally from the recorder. Correlation of the FDR data to the event local time, mountain daylight time (MDT), was established by using the FDR recorded GMT hour, minute and second time parameters and then applying an additional -6 hour offset to change GMT to local MDT time.

MEDICAL AND PATHOLOGICAL INFORMATION

Both pilots completed company drug screening tests on July 8, 2016. Results of these tests for both pilots were negative. The captain told NTSB investigators that he was wearing his glasses, as required by his medical certificate.

ADDITIONAL INFORMATION

FAA Order 7110.65 specified phraseology to warn pilots of similar airports is contained is paragraph 7-4-3g: In those instances where airports are located in close proximity, also provide the location of the airport that may cause the confusion. EXAMPLE- "Cessna Five Six November, Cleveland Burke Lakefront Airport is at 12 o'clock, 5 miles. Cleveland Hopkins Airport is at 1 o'clock 12 miles. Report Cleveland Hopkins in sight."

Aviation Safety Reporting System (ASRS) Reports

A review of wrong airport landing data provided by ASRS revealed that in the previous 20 years approximately 600 wrong airport landings or near landings had been voluntarily reported. Of those, 6 occurred while attempting to land at RAP and resulted in a landing or landing attempt at RCA. Four of those reported were conducted by general aviation aircraft, which consisted of piston and turbojet aircraft, and two of those events were done during commercial air carrier passenger operations.

Previous "Wrong Airport" Incidents Involving RAP and RCA

According to information provided by Ellsworth, similar incidents of pilot confusion between RAP and RCA have occurred in the past, ending in either an unauthorized landing at RCA or a low approach to RCA before the mistake was identified and corrected by ATC or the pilot. For example, on August 17, 2015, a Hawker business jet inbound to the area from the west was vectored northwest of RCA for a visual approach to RAP. The crew misidentified RCA as their destination and completed an unauthorized landing. On June 19, 2004, a Northwest Airlines Airbus A319 also completed an unauthorized landing at RCA after the crew confused RCA with RAP. Ellsworth reported that pilot confusion between RAP and RCA continues to be fairly common, although the problem is typically detected and corrected by ATC or the crew before landing.

NTSB Wrong Airport Landing Investigations

DCA14IA037

On January 12, 2014, about 1808 CST (0008Z), Southwest Airlines flight 4013, a Boeing 737-7H4, N272WN, mistakenly landed at M. G

NTSB Probable Cause

The flight crew's misidentification of the desired landing runway due to excess altitude requiring an extended downwind, and failure to use all available navigation information.
