NTSB Factual Report

HISTORY OF FLIGHT

On June 9, 2011, about 1014 eastern daylight time, a Cessna 152, N48869, registered to N70FT Incorporated, and operated by Space Coast Aviation, collided with the ground after a loss of control in flight, in Vero Beach, Florida. The personal flight was operated under the provisions of Title 14 Code of Federal Regulations Part 91, and no flight plan was filed. The certificated private pilot and passenger were fatally injured, and the airplane sustained substantial damage. The airplane departed from Merritt Island Airport (COI), Merritt Island, Florida, about 0930. There were no reported witnesses to the accident.

According to personnel at Space Coast Aviation, the flight was due back at COI at 1400. About 1500, they began calling other airports trying to locate the airplane, and contacted cell phone companies in an attempt to locate the pilot by her cell phone. The Federal Aviation Administration (FAA) issued an Alert Notice (ALNOT) and a search was initiated at 1920.

At 2130, the Civil Air Patrol (CAP) was notified of the missing airplane and obtained a mission briefing. The Incident Commander (IC) contacted the flight school at COI and was given the airplane’s probable flight path. He was informed that no flight plan was filed and no flight plan was left at the flight school. The IC launched aircraft on a probable flight path from COI to OBE at 2230, based on information from the flight school. A law enforcement detective called and informed the IC that a phone company had found a cell tower location, at the Yeehaw Junction Tower, located at N27 40.29, W080 48.35. The detective notified the Osceloa County Sheriff concerning a possible search area for the missing aircraft. The Air Force Rescue Coordination Center (AFRCC) then informed the IC of a location and probable flight path, based on radar data. At 00:30, the AFRCC sent an email to the IC of radar returns. The path started at COI and terminated at the southern edge of Blue Cypress Lake, just northeast of the Yeehaw Junction Tower and on a flight path between COI and OBE. Civil Air Patrol aircraft made radio contact with the Indian River Sheriff’s helicopter about 0115 and had acquired a weak emergency locator Transmitter (ELT) signal. The Indian River Sheriff's aircrew located the wreckage about 0154.

Review of radar data revealed that at 10:12:02, the airplane made a right 70-degree turn to a heading of 180 degrees. At 10:14:26, the airplane then made a left 360-degree turn. The last radar return was at 10:14:26.

A FAA inspector, who interviewed an FAA radar specialist that obtained radar data from a facility located 10 miles from the accident site, stated the radar specialist informed him the airplane's altitude information was missing and the airplane had a ground speed of approximately 90 to 95 knots for almost the entire time of the flight. In addition, he stated, "The ground speed gets very slow right at the very end of the flight path; that is, on the very last radar return."

WRECKAGE INFORMATION

The wreckage was located .20 mile southwest of Blue Cypress Lake in the vicinity of Vero Beach, Florida. Examination of the crash site revealed the airplane collided with trees and a swamp in a nose down attitude left wing low and came to rest on a heading of 320 degrees magnetic. There was no crash debris line. The propeller spinner was crushed. The propeller remained attached to the crankshaft flange by one propeller bolt. The remaining bolts were unbroken, but the propeller flange bushings were fractured. The propeller flange was bent. One propeller blade exhibited paint scuffing on the leading edge. The remaining propeller blade was bent aft about 20 degrees at about 18 inches outboard of the hub. The engine cowling was damaged and remained attached to the engine. The engine assembly remained attached to the engine mounts and the firewall. The propeller assembly and engine assembly and accessories were buried 3 feet below the surface of the ground with the accessory case level with the ground.

The windshield was destroyed. The cabin doors were opened and remained attached at their hinge points. Both door windows were broken and both door latches were in the latched position. The instrument panel was fragmented. The attitude indicator indicated 5 degrees pitch up, and 5 degrees left wing low. The vertical speed indicator indicated 2,000 feet-per-minute down. The stall warning horn was an aural device. It was checked and functioned. The fuel selector valve was in the on position. The throttle and mixture control was full forward. The left and right cabin seats remained attached to the seat tracks. Both seatbelts and shoulder harness were in use. Continuity of the flight control surfaces was established from all flight control surfaces to the cockpit controls. The rear baggage compartment window was shattered. The left and right main landing gear remained attached to the fuselage and was buried below the surface of the ground.

The right wing remained attached at the wing root. The leading edge of the right wing sustained accordion crush damage from the wing root, extending outboard to the wing tip. The right wing tip remained attached but was damaged. The upper wing skin sustained minor damage. The lower skin sustained accordion wrinkles from the leading edge to the rear spar. The right main fuel tank was ruptured with evidence of hydraulic action. The right main fuel cap was removed and had a tight seal. No browning of vegetation was present at the crash site. The right flap remained attached sustained minor damage and was in the retracted position. The right aileron remained attached at all hinge points and sustained minor damage.

The carburetor was disassembled and a small amount of blue liquid with an odor consistent with that of aviation gasoline was present. No debris was present in the carburetor fuel inlet screen. Compression was noted on the outboard sides of the brass floats. A check of the liquid with water finding paste revealed no indication of the presence of water.

The left magneto remained attached to the engine and was not damaged. The right magneto mounting flange was fractured and the magneto was partially separated from the engine. Both magnetos were removed and rotated by hand. Both magnetos produced spark from all ignition towers. The ignition harness was damaged. The upper spark plugs were removed and exhibited light gray coloration of the electrodes and worn normal condition when compared to the Champion Check-A-Plug chart. The lower were removed and exhibited light gray to light brown coloration and worn normal condition. Lead deposits were noted in the electrode wells of the lower. The electrode gaps were inconsistent.

The starter and alternator remained attached to the engine. Radial score marks were noted on the starter nose case. The alternator was damaged. The alternator belt remained in place and was broken. The vacuum pump remained attached to the engine and was removed and disassembled. The carbon rotor, carbon vanes and the drive coupling were intact.
