# NTSB ANC03LA002: Piper PA-22, N7027D, Wasilla, AK, October 11, 2002 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 10, 2002, 18:40 local (Oct 11, 2002, 02:40 UTC) - Place: Wasilla, AK - Coordinates: 61.575553, -146.545272 - Nearby events: https://openairdocs.org/map.md?lat=61.5756&lon=-146.5453&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report July 23, 2003 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - Parties: Federal Aviation Administration - NTSB case key (mKey): 55873 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC03LA002 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/55873/pdf - Page: https://openairdocs.org/ntsb/ANC03LA002 ## Probable cause The instructor's inadequate supervision of the pilot-rated dual student, and the dual student's excessive use of brakes during the landing roll, which resulted in the nose over of the airplane. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Nose over, landing - roll - supervision - inadequate, pilot in command(cfi) (cause) - brakes(normal) - excessive, dual student (cause) ## Analysis The flight instructor, seated in the right seat, was providing flight instruction/recurrent training to the private pilot, seated in the left seat, in a wheel-equipped airplane converted to a tailwheel configuration. The private pilot had accomplished two successful stop-and-go landings prior to the accident landing. On the third landing, during landing roll on a dry paved runway, the private pilot allowed the airplane to veer slightly to the left of the runway's centerline. The flight instructor attempted to realign the airplane by applying a slight amount of right rudder, the private pilot simultaneously applied heavy braking, and both wheels locked. The airplane subsequently nosed over, and sustained substantial damage to the wings, fuselage, and empennage. The flight instructor noted that there were no preaccident mechanical anomalies with the airplane. ## Factual narrative On October 10, 2002, about 1840 Alaska daylight time, N7027D, a wheel-equipped Piper PA-22 airplane converted to a tailwheel configuration, sustained substantial damage during landing at the Wasilla Airport, Wasilla, Alaska. The airplane was being operated as a visual flight rules (VFR) local area instructional flight under Title 14, CFR Part 91, when the accident occurred. The first pilot, seated in the right seat, a certificated flight instructor, and the second pilot seated in the left seat, a certificated private pilot, were not injured. Visual meteorological conditions prevailed, and no flight plan was filed. The flight originated at the Palmer Airport, Palmer, Alaska, about 1800. During a telephone conversation with a National Transportation Safety Board investigator on October 16, the first pilot reported that she was providing flight instruction/recurrent training to the second pilot. She added that the second pilot had accomplished two successful stop-and-go landings prior to the accident landing. The first pilot said that just after landing on runway 03, a dry paved runway, the second pilot allowed the airplane to veer slightly to the left of the runway's centerline. She said that while she attempted to realign the airplane by applying a slight amount of right rudder, the second pilot simultaneously applied heavy braking, and both wheels locked. The airplane subsequently nosed over, and sustained substantial damage to the wings, fuselage, and empennage. The first pilot noted that there were no preaccident mechanical anomalies with the airplane. ## Aircraft - Registration: [N7027D](https://openairdocs.org/aircraft/N7027D), registered now, S/N 22-4921, built 1956 (OpenAirDocs) - Reported make and model: Piper PA-22 - Registry model: [Piper PA-22-150](https://openairdocs.org/model/piper-pa-22-150) (registry code 7102210) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 22-4921 - Airframe hours: 4141.1 - Engines: Lycoming O-320 150 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: William B.
