# NTSB LAX97LA041: Beech F33A, N1567P, Marana, AZ, November 14, 1996 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: November 14, 1996, 11:25 local (18:25 UTC) - Place: Marana, AZ - Coordinates: 32.450042, -111.289695 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=32.4500&lon=-111.2897&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report August 21, 1997 - Report: Approved by Office Director - NTSB case key (mKey): 29684 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX97LA041 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/29684/pdf - Page: https://openairdocs.org/ntsb/LAX97LA041 ## Probable cause improper planning/decision by the flight instructor (CFI), which resulted in his failure to recover from a descent during demonstration of a simulated (engine-out) emergency procedure. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with terrain/water, takeoff - weather condition - high density altitude - emergency procedure - simulated, pilot in command(cfi) - planning/decision - improper, pilot in command(cfi) (cause) - descent - not corrected, pilot in command(cfi) (cause) ## Analysis The flight instructor reported that following some air work, the flight proceeded to the Avra Valley Airport where two touch-and-go landings were accomplished, followed by a full stop landing. The student taxied the aircraft back for takeoff, and the instructor took control to demonstrate procedures for an engine failure during the takeoff initial climb. The instructor stated that following a high performance takeoff, 'the airplane climbed to 50 to 100' AGL, at which time I smoothly reduced throttle to idle and lowered nose below level pitch. Airplane began to descend rapidly and I realized that the sink rate was quite large. I applied full throttle and raised nose to attempt to reduce sink. The airplane impacted the ground in approx. level attitude, the nose gear collapsed and the plane slid to a stop in approximately a few hundred feet.' The temperature was reported to be 81 degrees Fahrenheit. Based upon this temperature and the estimated pressure altitude, the density altitude was calculated to be 3,892 feet. ## Factual narrative On November 14, 1996, at 1125 hours mountain standard time, a Beech F33A, N1567P, collapsed the landing gear and damaged the wings during a hard landing at the Avra Valley, Arizona airport. The aircraft was owned and operated by Air Transport Training International, Inc., of Tucson, Arizona, and was engaged in a dual primary instructional flight. Visual meteorological conditions prevailed at the time and no flight plan was filed for the operation. The aircraft incurred substantial damage in the crash. The certificated airline transport pilot flight instructor and the dual primary student were not injured. The flight originated at the Ryan airport, Tucson, on the day of the accident at 1025. In his written statement, the flight instructor reported that following some air work, the flight proceeded to the Avra Valley airport where two touch-and-go landings were accomplished, followed by a full-stop landing. The student taxied the aircraft back for takeoff and the instructor took control to demonstrate procedures for an engine failure during the takeoff initial climb. The instructor stated that following a high performance takeoff, "the airplane climbed to 50 to 100' AGL, at which time I smoothly reduced throttle to idle and lowered nose below level pitch. Airplane began to descend rapidly and I realized that the sink rate was quite large. I applied full throttle and raised nose to attempt to reduce sink. The airplane impacted the ground in approx. level attitude, the nose gear collapsed and the plane slid to a stop in approximately a few hundred feet." The temperature at the time the accident occurred was 81 degrees Fahrenheit. Based upon this temperature and the estimated pressure altitude, the density altitude was calculated to be 3,892 feet msl. ## Aircraft - Registration: [N1567P](https://openairdocs.org/aircraft/N1567P), registered now, S/N CE-1296, built 1988 (OpenAirDocs) - Reported make and model: Beech F33A - Registry model: [Beech F33A](https://openairdocs.org/model/beech-f33a) (registry code 1151425) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: CE-1296 - Engines: Continental IO-520-BB18B 285 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Air Transport Training Int - Airworthiness certificate: Standard, Normal; Standard, Utility - Departed: E14, MIRANA, AZ - Airport: E14, Avra Valley, runway 12, 6,901 × 100 ft, asphalt ## Flight crew As NTSB recorded them.

CFI demo engine out on takeoff. Got high sink rate. Impact level. Folded nose gear. Density altitude a factor. 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.
