# NTSB DEN01LA140: Maule MT-7-235, N116CP, Las Cruces, NM, August 4, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 4, 2001, 13:00 local (19:00 UTC) - Place: Las Cruces, NM - Coordinates: 32.260463, -106.819946 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=32.2605&lon=-106.8199&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report September 20, 2002 - Report: Approved by Office Director - Parties: FAA FSDO - NTSB case key (mKey): 52961 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN01LA140 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/52961/pdf - Page: https://openairdocs.org/ntsb/DEN01LA140 ## Probable cause The pilot's failure to properly recover from a bounced landing. Contributing factors include his misjudgment of the flare and his lack of total experience in make and model. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - aircraft control - not maintained, pilot in command (cause) - lack of total experience in type of aircraft, pilot in command (contributing factor) - porpoise/pilot-induced oscillation - encountered, pilot in command (contributing factor) - recovery from bounced landing - not performed, pilot in command (contributing factor) - procedures/directives - not followed, pilot in command (contributing factor) - Gear collapsed, landing - roll ## Analysis The airplane landed hard and porpoised several times. The final impact with the runway collapsed the nose landing gear. The airplane sustained substantial damage to the firewall and nose landing gear. The pilot reported 2,200 hours of total flight time in all aircraft and 11 hours of flight time in make and model. ## Factual narrative On August 4, 2001, at approximately 1300 mountain daylight time, a Maule MT-7-235, N116CP, operated by National Headquarters Civil Air Patrol (CAP), was substantially damaged during a hard landing at Las Cruces International Airport, Las Cruces, New Mexico. The pilot was not injured. Visual meteorological conditions prevailed, and no flight plan was filed for this repositioning flight being conducted under Title 14 CFR Part 91. The flight departed Las Cruces at approximately 1230. According to the pilot, he was returning from a glider tow operation and was landing on runway 22. He deployed full flaps, "4th notch," for the approach. The airplane landed hard and porpoised several times. The final impact with the runway collapsed the nose landing gear. The airplane sustained substantial damage to the firewall and nose landing gear. Witnesses corroborated the pilot's accident report. According to the Pilot/Operator Aircraft Accident Report (NTSB form 6120.1/2), the pilot reported 2,200 hours of total flight time in all aircraft and 11 hours of flight time in make and model. According to the "Normal Procedures" in Section III of the Federal Aviation Administration (FAA) approved Airplane Flight Manual, the recommended flap setting for landing is "Normally third notch (40 degrees/full flaps) - other positions permissible." A manufacturer's representative stated that, the Maule MT-7-235, is normally equipped with a flap configuration providing only "three notches" of flap selection and that the use of a specific flap selection for landing is "optional." He also stated that different versions of the Maule can be equipped with a flap configuration providing a "fourth notch." Weather at the time of the accident was, wind, 300 degrees at 3 knots; visibility, 10 statute miles; temperature, 31 degrees Celsius; dew point, 9 degrees Celsius; and an altimeter setting of 30.15. The airport elevation is 4,454 feet mean sea level (msl). The calculated density altitude is 7,187 feet msl. ## Aircraft - Registration: [N116CP](https://openairdocs.org/deregistered/N116CP-2011-01-07), registration cancelled 2011-01-07, S/N 18063C (OpenAirDocs) - Reported make and model: Maule MT-7-235 - Registry model: [Maule MT-7-235](https://openairdocs.org/model/maule-mt-7-235) (registry code 5460175) (OpenAirDocs) - Category: Airplane - Serial number: 18063C - Airframe hours: 46 - Engines: Lycoming IO-540-WIA5 235 horsepower reciprocating - Damage: Substantial damage - Flight: Public aircraft, Part 91 - Registered owner: National Headquarters CAP - Airworthiness certificate: Standard, Utility - Last inspection: Annual, March 30, 2001, 46 hours before - Departed: LRU, Las Cruces, NM - Destination: LRU, Las Cruces, NM - Airport: LRU, Las Cruces International, runway 22, 7,503 × 100 ft, asphalt ## Flight crew As NTSB recorded them.

(.19) On August 4, 2001, at approximately 1300 mountain daylight time, a Maule MT-7-235, N116CP, was substantially damaged during landing at Las Cruces… 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
