# NTSB LAX03LA148: Cessna 152, N48796, Pala, CA, May 6, 2003 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: May 6, 2003, 12:00 local (19:00 UTC) - Place: Pala, CA - Coordinates: 33.383335, -117.050003 - Nearby events: https://openairdocs.org/map.md?lat=33.3833&lon=-117.0500&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 2 minor - Status: Completed, report September 1, 2004 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 56969 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX03LA148 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/56969/pdf - Page: https://openairdocs.org/ntsb/LAX03LA148 ## Probable cause the dual student's delay in executing the proper recovery procedures and improper retraction of the flaps, the CFI's inadequate supervision during the recovery to normal flight, the CFI's delayed remedial action, and the failure of both pilots to maintain an adequate airspeed, which resulted in a stall-mush and collision with trees. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, maneuvering - emergency procedure - simulated, dual student - raising of flaps - improper, dual student (cause) - supervision - inadequate, pilot in command(cfi) (cause) - remedial action - delayed, pilot in command(cfi) (cause) - airspeed - not maintained, flightcrew (cause) - stall/mush - encountered - In flight collision with object, descent - uncontrolled - object - tree(s) ## Analysis The airplane collided with trees near a rock quarry while practicing a simulated engine out forced landing procedure. When the certified flight instructor (CFI) called for a termination of the maneuver the pilot under instruction (PUI) delayed executing the proper go-around procedures. The student left the flaps at the 30-degree position, and the airspeed got slow enough to activate the stall warning horn. The CFI called for the flaps to 20 degrees and to maintain airspeed. The CFI then called for flaps 10 degrees, but the student retracted them to 0 degrees. The airplane entered an excessive sink rate, and the CFI was unable to recover before the airplane impacted trees. ## Factual narrative On May 6, 2003, about 1200 Pacific daylight time, a Cessna 152, N48796, collided with trees and terrain while practicing emergency procedures near Pala, California. Pinnacle Aviation Services, Inc., was operating the airplane under the provisions of 14 CFR Part 91. The certified flight instructor (CFI) pilot and the private pilot under instruction (PUI) sustained minor injuries; the airplane was substantially damaged. The local instructional flight departed Carlsbad, California, about 1000. Day visual meteorological conditions prevailed, and no flight plan had been filed. The primary wreckage was at 33 degrees 23.0 minutes north latitude and 117 degrees 03.0 minutes west longitude. The CFI reported that the purpose of the flight was to practice emergency procedures. In the area of a rock quarry, they were performing a simulated engine out procedure. When the CFI called for a termination of the maneuver, he said that the PUI delayed in executing the proper go-around procedures. The PUI left the flaps at the 30-degree position, and the airspeed got slow enough to activate the stall warning horn. The CFI called for the flaps to 20 degrees and to "maintain airspeed." The CFI then called for flaps to 10 degrees, but the PUI mistakenly retracted them to 0 degrees. The airplane established a sink rate, and the CFI was unable to recover before the airplane impacted trees. The airplane came to rest approximately 50 yards from a dirt road. The airplane was destroyed during the impact sequence. Investigators from the Federal Aviation Administration examined the wreckage at the accident scene. They noted no pre-impact discrepancies with the airframe or the engine. The CFI and the PUI reported no mechanical malfunctions or failures with the airplane. ## Aircraft - Registration: [N48796](https://openairdocs.org/deregistered/N48796-2005-09-27), registration cancelled 2005-09-27, S/N 15283377, built 1979 (OpenAirDocs) - Reported make and model: Cessna 152 - Registry model: [Cessna 152](https://openairdocs.org/model/cessna-152) (registry code 2071835) (OpenAirDocs) - Registry engine: [Lycoming 0-235 series](https://openairdocs.org/engine/lycoming-0-235-series) (registry code 41505, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 15283377 - Airframe hours: 3940 - Engines: Lycoming O-235-L2C 110 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Pinnacle Aviation Services Inc - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, April 21, 2003, 28 hours before - Departed: CRQ, Carlsbad, CA ## Flight crew As NTSB recorded them.
