# NTSB CHI99LA277: Cessna 150M, N3755V, Sikeston, MO, August 6, 1999 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 6, 1999, 15:30 local (20:30 UTC) - Place: Sikeston, MO - Coordinates: 36.880786, -89.580688 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.8808&lon=-89.5807&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report June 22, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 46999 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI99LA277 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/46999/pdf - Page: https://openairdocs.org/ntsb/CHI99LA277 ## Probable cause the loss of engine power due to the stuck exhaust valve. A factor was the lack of suitable terrain available for the forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - mech failure/malf, takeoff - engine assembly,valve,exhaust - seized (cause) - Forced landing, emergency landing after takeoff - Nose over, landing - roll - terrain condition - soft - terrain condition - none suitable (contributing factor) ## Analysis The CFI reported that the engine was operating normally during run-up and takeoff. He reported that at about 200 feet above ground altitude, the engine started running rough. He applied carburetor heat and nosed the airplane over to maintain airspeed. The airplane continued to descend even though the pilot had applied full power. The CFI decided to land the airplane in a field at the end of the runway. He used full flaps and landed the airplane in the soft field. The airplane nosed over during landing rollout. An inspection of the engine revealed that one of the cylinders had an exhaust valve stuck in the open position. The owner and operator of the airplane reported that during the last 100 hour inspection, the cylinder with the stuck valve had a compression reading of 68 psi, just slightly lower than the other three cylinders. ## Factual narrative On August 6, 1999, at 1530 central daylight time, a Cessna 150M, N3755V, operated by Jolliff Aviation was substantially damaged when it experienced a loss of engine power on takeoff and nosed over in a soft field after a forced landing. The 14 CFR Part 91 flight had departed Sikeston Memorial Airport, Sikeston, Missouri, on a local instructional flight. The Certified Flight Instructor (CFI) and student pilot were not injured. Visual meteorological conditions prevailed and no flight plan was filed. The CFI reported that the engine was operating normally during run-up and takeoff.

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.
