# NTSB SEA03LA064: Cessna 150, N7057F, Coos Bay, OR, April 19, 2003 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: April 19, 2003, 13:30 local (20:30 UTC) - Place: Coos Bay, OR - Coordinates: 43.36861, -124.101669 - Nearby events: https://openairdocs.org/map.md?lat=43.3686&lon=-124.1017&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 2 serious - Status: Completed, report November 25, 2003 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 56864 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA03LA064 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/56864/pdf - Page: https://openairdocs.org/ntsb/SEA03LA064 ## Probable cause The pilot's improper remedial action during takeoff and his failure to maintain airspeed. Contributing factors included the binding of the left brake and the trees. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, takeoff - roll/run - landing gear,normal brake system - binding(mechanical) (contributing factor) - In flight collision with object, takeoff - initial climb - remedial action - improper, pilot in command (cause) - airspeed - not maintained, pilot in command (cause) - stall/mush - encountered, pilot in command - object - tree(s) (contributing factor) ## Analysis After adding takeoff power the pilot noticed the plane was not accelerating, and that a dragging left brake was pulling it to the left. Halfway down the runway the pilot decided to abort the takeoff, but then realizing he didn't have room to stop, decided to continue the takeoff. Rotating late, the pilot pulled back on the yoke a little too hard which resulted in the tail striking the ground. The aircraft then came off the ground, hit some berry bushes, some trees, then impacted the top of another tree causing the airplane to stall. The airplane impacted the ground in a nose down attitude, coming to rest on a 20-degree down slope of a ravine. Both wings and the firewall were substantially damaged. The pilot's son, also a pilot, said he had experienced similar problems with the left brake on previous occasions, stating that they would taxi the airplane until the brake was free. A post accident examination of the left brake revealed no anomalies which would have prevented normal operations. ## Factual narrative On April 19, 2003, approximately 1330 Pacific daylight time, a Cessna 150 single-engine airplane, N7057F, registered to a private individual and being flown by a student pilot, sustained substantial damage after impacting terrain while taking off at a private airstrip near Coos Bay, Oregon. The student pilot and his one passenger were seriously injured. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight being conducted under 14 CFR Part 91. The flight was originating at the time of the accident. In a telephone interview and according to the Pilot/Operator Aircraft Accident Report (NTSB form 6120.1/2), the pilot reported that when he "powered up for takeoff" he noticed the plane was "gaining speed too slow" and found the left brake caliper dragging and the airplane pulling to the left. The pilot further reported that about halfway down the runway he realized the airplane was not gaining speed and decided to abort the takeoff. He said he subsequently realized that he didn't have room to stop, at which time he added full power and "decided to take off." The pilot reported that he "rotated late and pulled back on the yoke a little too hard," which resulted in the tail striking the ground. The pilot stated the airplane then came off the ground, hit some berry bushes, some trees, then impacted the top of another tree when "the airplane stalled and the nose went down." The pilot further reported "the airplane was fine while I was taxiing for takeoff and the engine was running great the whole time." In a statement provided to an FAA inspector, the pilot's son, who is also a pilot, stated that he had experienced problems with the left brake dragging on a previous occasion, and that "in similar situations they would taxi the aircraft until the brake was free." The pilot's son also reported that operations on the accident date were similar to previous operations where the brake had been dragging. An FAA inspector, who traveled to the accident site, reported the airplane had come to rest on what was approximately a 20-degree down slope of a ravine. The aircraft was intact, with the exception of the pilot's door, which was located 10 feet from the aircraft. The aircraft's engine was reported buried in approximately 3 feet of water, and the propeller was damaged. The left aileron, both wings and the firewall sustained substantial damage. The inspector also reported that an examination of the left brake did not reveal any anomalies which would have prevented normal operations. ## Aircraft - Registration: [N7057F](https://openairdocs.org/deregistered/N7057F-2004-05-10), registration cancelled 2004-05-10, S/N 15063657, built 1966 (OpenAirDocs) - Reported make and model: Cessna 150 - Registry model: [Cessna 150F](https://openairdocs.org/model/cessna-150f) (registry code 2071814) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15063657 - Engines: Continental O-200 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Gary L.

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.
