# NTSB CHI99LA281: Cessna 150M, N66271, Perry, IA, August 9, 1999 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 9, 1999, 16:30 local (21:30 UTC) - Place: Perry, IA - Coordinates: 41.839981, -94.089897 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=41.8400&lon=-94.0899&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report June 22, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 47001 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI99LA281 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/47001/pdf - Page: https://openairdocs.org/ntsb/CHI99LA281 ## Probable cause the student pilot's inadequate compensation for the wind conditions which resulted in her failure to maintain control of the airplane. A factor associated with the accident was the gusty crosswind condition. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, landing - flare/touchdown - weather condition - gusts (contributing factor) - weather condition - crosswind (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - aircraft control - not maintained, pilot in command (cause) - On ground/water encounter with terrain/water, landing - roll - terrain condition - crop ## Analysis The student pilot reported that she set up for the landing on runway 13 with 20 degrees of flaps at 60 knots. She stated that during the landing, a gust of wind blew the airplane to the left of the runway. The student pilot reported she applied full power and lowered the nose. The airspeed was still 60 knots and the stall horn was sounding when the airplane was '...thrown to left and down.' She reported the airplane 'hit ground, bounced hard' then became airborne with the stall horn still sounding and the airspeed remaining at 60 knots. She reported she lowered the nose and the airplane once again contacted the ground and became airborne. The airplane then 'hit hard' and came to rest in a soy bean field. The winds reported at an airport 33 miles northeast of the accident site, 15 minutes after the accident , were from 200 degrees at 12 knots gusting to 19 knots. ## Factual narrative On August 9, 1999, at 1630 central daylight time, a Cessna 150M, N66271, sustained substantial damage during a hard landing on runway 13 (4,000' x 75') at the Perry Muncipal Airport, Perry, Iowa. The student pilot was not injured. The 14 CFR Part 91 solo instructional flight was operating in visual meteorological conditions without a flight plan. The flight originated from Des Moines, Iowa, at 1600 cdt. The student pilot reported that she set up for the landing on runway 13 with 20 degrees of flaps at 60 knots. She stated that during the landing, a gust of wind blew the airplane to the left of the runway. The student pilot reported she applied full power and lowered the nose. The airspeed was still 60 knots and the stall horn was sounding when the airplane was "...thrown to left and down." She reported the airplane "hit ground, bounced hard" then became airborne with the stall horn still sounding and the airspeed remaining at 60 knots. She reported she lowered the nose and the airplane once again contacted the ground and became airborne. The airplane then "hit hard" and came to rest in a soy bean field. The winds reported at the Boone Muncipal Airport, 33 miles northeast of the accident site, at 1645 cdt, were from 200 degrees at 12 knots gusting to 19 knots. ## Aircraft - Registration: [N66271](https://openairdocs.org/aircraft/N66271), registered now, S/N 15075969, built 1974 (OpenAirDocs) - Reported make and model: Cessna 150M - Registry model: [Cessna 150M](https://openairdocs.org/model/cessna-150m) (registry code 2071830) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15075969 - Airframe hours: 9186 - Engines: Continental O-200-A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Foxtrot Flying Club, Inc. - Airworthiness certificate: Standard, Normal - Departed: DSM, DES MOINES, IA - Destination: PRO - Airport: PRO, Perry Municipal, runway 13, 4,000 × 75 ft, asphalt ## Flight crew As NTSB recorded them.

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.
