# NTSB LAX98LA224: Taylorcraft BL-65, N23670, Livermore, CA, July 5, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 5, 1998, 11:20 local (18:20 UTC) - Place: Livermore, CA - Location: 37.6870° N, 121.7598° W: Placed by OpenAirDocs: center of Livermore, CA, within about 6 miles (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=37.6870&lon=-121.7598&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report February 16, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 30141 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX98LA224 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/30141/pdf - Page: https://openairdocs.org/ntsb/LAX98LA224 ## Probable cause The pilot's failure to maintain adequate clearance from the trees. A related factor was the mountainous terrain. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, maneuvering - terrain condition - mountainous/hilly - altitude/clearance - inadequate, pilot in command (cause) - object - tree(s) ## Analysis During a photographing flight in hilly terrain, the pilot applied full power, but the aircraft was unable to establish a positive rate of climb. The pilot reported that the aircraft was unable to clear the terrain and he made a forced landing into a tree. The pilot reported no mechanical malfunctions. An engine run was conducted with no abnormalities noted. ## Factual narrative On July 5, 1998, at 1120 hours Pacific daylight time, a Taylorcraft BL-65, N23670, experienced a loss of engine power during cruise and came to rest inverted after colliding with trees near the San Antonio Reservoir, Livermore, California. The aircraft, operated under the provisions of 14 CFR Part 91, sustained substantial damage. The private pilot and one passenger were not injured. Visual meteorological conditions existed for the personal flight and no flight plan was filed. The pilot reported that after departing the Livermore airport he flew to Pleasanton so that his passenger could take some photographs, and then flew to the reservoir to take some more photographs. He stated that the area they were flying in was hilly terrain. The pilot reported that he applied full power but was unable to establish a positive rate of climb. He further reported that the engine did not seem to be generating normal horsepower and he was unable to clear the hilly terrain. He made a forced landing in a tree and both he and his passenger were able to egress without further incident and hiked to the nearest road. In the pilot's report to the Safety Board he reported that there were no mechanical malfunctions noted with the engine. A Federal Aviation Administration inspector from the Oakland, California, Flight Standards District Office examined the engine. He reported that an engine run was conducted with no abnormalities noted. ## Aircraft - Registration: [N23670](https://openairdocs.org/aircraft/N23670), registered now, S/N 1403, built 1939 (OpenAirDocs) - Reported make and model: Taylorcraft BL-65 - Registry model: [Taylorcraft BL-65](https://openairdocs.org/model/taylorcraft-bl-65) (registry code 8850350) (OpenAirDocs) - Registry engine: [Lycoming 0-145B series](https://openairdocs.org/engine/lycoming-0-145b-series) (registry code 41502, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: BL 65 - Engines: Lycoming O-145-B2 65 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Kenneth M.

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.
