# NTSB ANC06LA035: Claypool RV-6A, N428BC, San Diego, CA, March 27, 2006 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: March 27, 2006, 13:00 local (21:00 UTC) - Place: San Diego, CA - Coordinates: 32.815555, -117.139442 - Nearby events: https://openairdocs.org/map.md?lat=32.8156&lon=-117.1394&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report August 29, 2006 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - Parties: Los Angeles - NTSB case key (mKey): 63406 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC06LA035 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/63406/pdf - Page: https://openairdocs.org/ntsb/ANC06LA035 ## Probable cause The pilot's improper recovery from a bounced landing, which resulted in a hard landing, the collapse of the nose landing gear, and a nose over. A factor associated with the accident was the pilot's failure to perform a go-around. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - recovery from bounced landing - improper, pilot in command (cause) - go-around - not performed, pilot in command (contributing factor) - Nose over, landing - roll - landing gear,nose gear - collapsed - terrain condition - runway ## Analysis The solo private pilot was landing on a hard surfaced runway at the conclusion of a Title 14, CFR Part 91 personal cross-country flight in an experimental, amateur built airplane. He said during landing he overshot the final approach course, and in an attempt to salvage the landing, he forgot to put in the last notch of flaps. He said the airplane crossed the threshold too fast and would not slow down. He stated that the airplane landed hard, and then porpoised. On the third bounce, he said the nose wheel collapsed, and the airplane nosed over. He said he should have gone around and reconfigured the airplane instead of attempting to land. The pilot reported that there were no mechanical anomalies with the airplane prior to the accident. He said the airplane sustained structural damage to the nose gear, wings, and fuselage. ## Factual narrative On March 27, 2006, about 1300 pacific standard time, an experimental amateur built, Claypool RV-6A airplane, N428BC, sustained substantial damage during a hard landing and a nose over at Montgomery Field, San Diego, California. The airplane was being operated by the pilot as a visual flight rules (VFR) personal cross-country flight under Title 14, CFR Part 91, when the accident occurred. The solo private pilot received minor injuries. Visual meteorological conditions prevailed, and no flight plan was filed. The flight departed the Fresno Airport, Fresno California, about 1100. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on March 30, the pilot said the airplane landed hard and bounced. He said the airplane came down nose wheel first and bounced again, and on the third bounce the nose wheel tucked under the airplane, and the airplane nosed over. The pilot said there were no mechanical anomalies with the airplane prior to the accident. He said the airplane sustained structural damage to the nose gear, wings, and fuselage during the accident. In a written statement to the NTSB dated April 3, the pilot wrote that he overshot the final approach course, and in an attempt to salvage the landing he forgot to put in the last notch of flaps, and crossed the runway threshold at 70 knots. He said once lined up with the runway, the airplane would not slow down. He reported that the airplane finally touched down hard, and then porpoised. He said each oscillation worsened until the airplane struck the runway and flipped over, about 2,000-2,500 feet down the runway. He reported he had several chances to go-around and reconfigure the airplane, but did not. ## Aircraft - Registration: [N428BC](https://openairdocs.org/deregistered/N428BC-2008-08-12), registration cancelled 2008-08-12, S/N 60038, built 2001 (OpenAirDocs) - Reported make and model: Claypool RV-6A - Registry model: [Claypool Robert Scott RV-6A](https://openairdocs.org/model/claypool-robert-scott-rv-6a) (registry code 05606S4) (OpenAirDocs) - Registry engine: [Lycoming I0360 SER A&C](https://openairdocs.org/engine/lycoming-i0360-ser-a-c) (registry code 41511, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 60038 - Airframe hours: 200 - Engines: Lycoming IO-360 210 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Robert Claypool - Last inspection: Annual, March 1, 2006 - Departed: KFCH, Fresno, CA - Destination: MYF, San Diego, CA - Airport: MYF, Montgomery field, runway 28L, 3,401 × 60 ft, asphalt ## Flight crew As NTSB recorded them.

(-23) Pilot landed hard, bounced, then bounced again, pilot lost control and aircraft flipped and ended up inverted. From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
