NTSB description


On July 1, 2005, at an estimated time of 1200 Alaska daylight time, a wheel-equipped Cessna T207 airplane, N1621U, was destroyed by impact and postimpact fire when it collided with the north side of West Amatuli Island, a part of the Barren Islands, located about 25 miles south-southeast of Nanwalek, Alaska. The airplane was being operated as a visual flight rules (VFR) local area personal flight under Title 14, CFR Part 91, when the accident occurred. The airplane was registered to Aero Tech Flight Service Inc., Anchorage, Alaska, and operated by the pilot. The airline transport certificated pilot, and the two pilot-rated passengers, received fatal injuries. Instrument meteorological conditions are presumed to have prevailed in the area of the accident. The flight originated at the Homer Airport, Homer, Alaska, on July 1, about 1105. No flight plan was filed, nor was one required.

On July 3, the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), was notified by Federal Aviation Administration (FAA) personnel that the accident airplane had been reported overdue. The wreckage of the airplane was located by a U.S. Coast Guard airplane on July 5, about 200 feet below the top of a ridge on the north face of West Amatuli Island. A U.S. Coast Guard helicopter was dispatched to the scene, but due to the steep terrain, did not land. An Air National Guard helicopter with pararescue personnel aboard was dispatched to the scene. They verified the airplane as the missing airplane and recovered the occupants.

According to information provided by Alaska State Troopers personnel, the pilot and the passengers traveled to Anchorage, Alaska, on June 25, 2005. Examination of a hand-written travel itinerary that was found by State Trooper personnel indicated the pilot and passengers planned to visit Juneau, Ketchikan, Sitka, and Homer, Alaska. Alaska State Troopers, and FAA personnel reported that the airplane arrived in Homer on the evening of June 29. On June 30, the airplane traveled to Kodiak, Alaska, and returned to Homer, and then conducted a flight during the evening hours of the 30th.

On July 1, at 0933, the pilot telephoned the Kenai Automated Flight Service Station (AFSS), Kenai, Alaska, and according to FAA transcrips of the recorded conversation, stated, in part: "...we're in Homer and we're wanting to do some flying sightseeing for the day, and just hope, wondering if you can point us toward the direction where we would have the best luck for VFR conditions."

The fight service station specialist replied, in part: "Well, it doesn't really look good probably anywhere today. Unfortunately, up in the Kenai area right now we've been IFR this morning. They do expect it to improve, but then we've got the fire up in the Sterling [Alaska] area, up in the Skilak [Alaska] area, and the one up in Hope [Alaska], so those gonna affect that. Then in the going the other direction, out further to the west, Big River Lakes is good in that area, but they've also been back and forth this morning, so right now they're marginal with visibility 4 [miles]. The Bristol Bay area is expected to stay that way pretty much, but they've got AIRMETS for IFR, and mountain obscurations over in that area, so you don't really wanna go to the Bristol Bay area. Kodiak, actually right now, looks probably about the best, heading south to Kodiak, cuz going up to Seward [Alaska] doesn't, which is unusual. Usually it's just the opposite, but if you go on up to the Seward area, they've got lower conditions and they're forecasting those for the central gulf coast to be a little bit lower today, which would...(unintelligible)...ceilings they're forecasting marginal VFR, some isolated IFR conditions over in that like I said, anywhere pretty much to the north it looks like it's gonna be worse for you looks better going, like I said, which is usually just the opposite, Kodiak actually looks better today."

The pilot replied, "Well, we flew down to Kodiak yesterday, and things were pretty good until we got there, and they had fog lying in, so the, you know the main field there was socked in with ah Special VFR." The AFSS specialist stated, "I'm checking right now, let's see what Kodiak, what their current conditions are and what the terminal [forecast] is...but yah, it looks like for today, the rest of the areas look pretty bad. Kodiak currently, visibility is 10 [miles], 8,500 [feet] broken, and the terminal [forecast] is calling for wind, 330 [degrees] at 10 [knots], visibility greater than 6 [miles], few clouds at 300 hundred [feet], 1,000 [feet] scattered, 4,000 [feet] broken, and then they expect it to improve after 2 p.m."

The pilot stated that "It sounds like they're clearly VFR right now," to which the AFSS specialist replied, "Right, it does look better going that direction today." The pilot then stated, "Okay, what do you have in terms of just, Oh I don't know the right term, I think it, an area prognostication, or whatever, we, we're trying to make a decision to get the plane up tomorrow or the next day, are things clearing at all or."

The specialist replied, in part: "Right now, looking at the surface charts, which gives us the best...indicator, there is some low pressure down in the Gulf of Alaska, but the charts show that moving off the east, so that actually looks pretty good for tomorrow for the Cook Inlet, Susitna Valley, as that moves out of the area. Then that next low pressure hopefully, is not gonna move in til Sunday, so looking at the charts for tomorrow morning, we have a low pressure ridge that's gonna lay from like the Y-K Delta, and then head up north and go across the area, but it looks better for tomorrow. Looking at the area forecast, in the outlook portion for tomorrow, the forecast for the Cook Inlet, Susitna Valley, they're forecasting the outlook for VFR with some rain showers, so it actually looks better tomorrow." The pilot concluded the briefing at 0937 by stating, "Okay, well that is certainly what we need to know, and you have been very helpful."

At 0942, the pilot telephoned the Kenai AFSS and requested the Kodiak Automated Surface Observing System (ASOS) telephone number.

At 1100, the pilot made radio contact the Homer Fight Service Station (FSS) specialist and stated, "Homer traffic, skywagon 1621U is taxiing to [runway] 21." At 1105, the pilot reported that he was on the takeoff roll.

The Barren Islands are located about mid-way between the south end of the Kenai Peninsula, and the north end of Kodiak Island, along the Kennedy Entrance to Cook Inlet. It is comprised of West and East Amatuli, Ushigat, Sugarloaf, Sud, and Nord Islands that are within the Alaska Maritime National Wildlife Refuge.


The pilot held an airline transport pilot certificate with airplane single-engine and multiengine land ratings. He also held a flight instructor certificate with airplane single-engine, and instrument airplane ratings. The most recent second-class medical certificate was issued to the pilot on June 7, 2005, and contained the limitation that the pilot must wear corrective lenses.

No personal flight records were located for the pilot and the aeronautical experience listed on page 3 of this report was obtained from a review of the airmen Federal Aviation Administration (FAA) records on file in the Airman and Medical Records Center located in Oklahoma City, Oklahoma. On the pilot's application for medical certificate, dated June 7, 2005, the pilot indicated that his total aeronautical experience consisted of about 8,432 hours, of which 254 were accrued in the previous 6 months.


The pilot rented the airplane from Aero Tech Flight Services Inc., Anchorage, Alaska. He received a VFR airplane check-out by an Aero Tech instructor on June 26. Aero Tech personnel reported that all of the airplane's maintenance logbooks were on board the airplane at the time of the accident.

Maintenance on the airplane was performed by Hanger 5, Anchorage. The facility had a copy of the most recent annual inspection check list, which was performed on July 1, 2004. At that time, the airplane had accrued 7,416 hours. The engine had accrued 5,944 hours, and 852.2 hours since an overhaul. Examination of previous discrepancies noted on the airplane revealed no unresolved maintenance issues.

According to company personnel from Homer Air, Homer, the airplane was fueled with 40 gallons of aviation fuel on June 30, 2005, about 0900. At that time, the pilot requested that a fuel account be opened. The airplane was again fueled on June 30, about 1830, with 36 gallons of aviation fuel after landing in Homer about 1748. The airplane was fueled on the morning of July 1, with 16 gallons of aviation fuel.


The closest official aviation weather observation station is Seldovia, Alaska, which is located 31 nautical miles north of the accident site.

At 0911, the FAA received a pilot weather report (PIREP) from a Cessna 185 on a flight from Homer to Kodiak. The pilot reported that south of Flat Island (located about 3 miles south of Nanwalek), there was fog and mist to the water. The pilot indicated that he was unable to maintain VFR, and was returning to Homer due to weather.

A PIREP was received by the FAA at 0906 from a Cessna 172 on a flight from Homer to Kenai. The pilot indicated that 5 miles north of Homer, he was unable to maintain VFR due to clouds to the ground.

At 0915, the pilot of a Cessna 180 on a flight from Homer to Kasilof, Alaska, filed a PIREP that indicated the sky condition was 800 feet overcast, with 10 miles of visibility via the coast.

The captains of two fishing charter vessels operating from Homer, reported that on the day of the accident, the weather conditions around the Barren Islands included fog that obscured the islands. One vessel captain reported hearing an airplane in the vicinity of the islands, but could not see it because of the fog.


After the pilot announced that he was departing runway 21 at Homer, no further communications were received from the airplane. The Homer FSS specialist reported that the pilot did not request a local airport advisory (LAA), or any other services.

A transcript of the communications between the airplane and all involved FAA ATC facilities is included in the public docket of this accident.


The NTSB IIC, accompanied by another NTSB air safety investigator, and an FAA inspector, examined the airplane wreckage at the accident site on July 6, 2005. The accident site was the north face of the island that extended from a small saddle at the top of the face, to the ocean shore. The face of the island was sloping terrain of about 40 degrees that consisted of tundra grasses, boulders, and rock scree. A path of wreckage debris from the initial impact site, about 200 feet below the top of the saddle, to the main fuselage wreckage point of rest, about another 200 feet downslope, was on a magnetic heading of 180 degrees. (All heading/bearings noted in this report are oriented toward magnetic north.)

All of the airplane's major components were found at the main wreckage area. The initial impact site was about 800 feet mean sea level, and had disruption of the ground and gouging of an area of rock, extensive presence of oil, and burned grass. Interior and exterior fragments of the forward portion of the airplane, including engine parts, windshield, rudder pedal fragments, radio components, and fragments of the trim wheel were located at the initial impact site. Additional fragmented parts of the airplane, and areas of burned grasses were evident from the initial impact site, directly downslope, to the fuselage point of rest. There was no lateral distribution of wreckage debris at the crash site from the main debris path.

The right main landing gear strut, with its wheel attached, portions of the cockpit area including instrument panel parts, and the separated propeller assembly, were located downslope, about half-way between the initial impact site and the fuselage point of rest. The left main landing gear strut remained attached to the fuselage.

Examination of the three-bladed propeller assembly revealed that it had fractured where the crankshaft exited the engine case. The propeller blades were loose in the hub. All of the blades had extensive leading edge gouging, chordwise scratching, "S" bending, torsional twisting, and fracturing of two of the three propeller tips. A portion of a separated propeller blade tip was located forward, and upslope from the initial impact site.

Below the propeller point of rest, portions of seat frames, and seat belts were found. These had evidence of fire damage to each, and the seat belts were latched, with one belt portion still attached to a fragment of floor structure.

The wings remained attached to the fuselage. Both were extensively crushed aft and folded parallel to the longitudinal axis of the fuselage. Each retained their respective aileron and flap assemblies.

The postcrash fire incinerated most of the cabin and cockpit area from the empennage forward. The fuselage had extensive aft crushing and fragmentation. The crown of the fuselage was destroyed by fire. Due to impact and postimpact fire damage, the flight controls could not be moved by their respective control mechanisms, but flight control cables were attached from the empennage to the cockpit.

The empennage, at the point of rest, was upright and had not sustained extensive destruction. The leading edge of the left horizontal stabilizer had aft crushing, and the outboard end of the right stabilizer was bent downward. The elevators and rudder remained attached to their respective attach points.

The engine sustained extensive impact and fire damage to the underside and front portion of the engine. The engine case and cylinders were fractured. One exhaust extension tube was crushed and folded nearly flat, producing sharp creases that were not cracked or broken along the creases.


A postmortem examination of the pilot was not cond
