# NTSB BFO95LA044: Cessna 152, N93874, Finksburg, MD, April 6, 1995 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: April 6, 1995, 14:52 local (18:52 UTC) - Place: Finksburg, MD - Coordinates: 39.490238, -76.880516 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.4902&lon=-76.8805&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 2 serious - Status: Completed, report November 30, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 9040 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=BFO95LA044 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9040/pdf - Page: https://openairdocs.org/ntsb/BFO95LA044 ## Probable cause loss of engine power for undetermined reasons. A related factor was the lack of suitable terrain. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, cruise - engine assembly,cylinder - low compression - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - On ground/water encounter with terrain/water, landing - terrain condition - none suitable (contributing factor) ## Analysis THE PILOT REPORTED THAT THE AIRPLANE WAS IN CRUISE FLIGHT AT 1500 FEET MSL WHEN THE ENGINE LOST PARTIAL POWER. ALL ATTEMPTS TO REGAIN ENGINE POWER WERE UNSUCCESSFUL. SHE STATED THAT SHE MADE A FORCED LANDING IN A FRESHLY PLOWED CORN FIELD, BUT DURING THE LANDING ROLL THE NOSEWHEEL COLLAPSED AND THE AIRCRAFT NOSED OVER. POSTACCIDENT EXAMINATION OF THE AIRPLANE FUEL SYSTEM REVEALED THAT FUEL WAS PRESENT IN THE FUEL LINES TO THE CARBURETOR. POSTACCIDENT EXAMINATION OF THE ENGINE AND ITS ACCESSORIES REVEALED NO EVIDENCE OF PREIMPACT MECHANICAL MALFUNCTION. HOWEVER, A COMPRESSION TEST WAS PERFORMED AND COMPRESSIONS OF 54/80; 18/80; 62/80 AND 66/80 WERE OBTAINED ON CYLINDERS 1 THROUGH 4, RESPECTIVELY. ## Factual narrative On April 6, 1995, at 1452 eastern daylight time, N93874, a Cessna 152, N93874, lost engine power and made a forced landing in the vicinity of Finksburg, Maryland. The aircraft was destroyed when it nosed over during the landing roll. The certificated private pilot and the one passenger were seriously injured. Visual meteorological conditions prevailed and a flight plan was not filed. The personal flight was conducted under 14 CFR Part 91 and originated at Martin State Airport in Baltimore, Maryland, at 1420. The intended destination was Carroll County Airport in Westminster, Maryland. The pilot reported that the flight was cruising at 1500 feet MSL when the engine "started missing and began to lose power." She stated that, "it was as if someone was taking the power away slowly." She reported that the loss of power occurred about 20 minutes after departure, and that all attempts to regain engine power using the emergency procedures were unsuccessful. The pilot stated: "Prior to shutting fuel and mags off, full throttle would only give us about 1300 RPM." She reported that during the forced landing the nosewheel collapsed and the aircraft nosed over, coming to rest inverted in the freshly plowed corn field. The airplane was examined at the accident site by two inspectors from the FAA. The examination confirmed control continuity of the flight controls. According to an aircraft mechanic who was asked by one of the FAA inspectors for assistance, while the airplane was inverted and tilted, the mechanic removed the cap from the "low" wing. He estimated that between five and ten gallons of fuel escaped before he could get the cap back on. The FAA Inspectors reported that when one of them removed the same cap, at a different time, approximately two gallons of fuel escaped. One of the FAA inspectors reported that there was "(f)uel in the gascolator, fuel in the left tank, unknown quantity but plenty to keep running, fuel in lines to bowl to carburetor, fuel line was not collapsed." The carburetor was impact damaged, and separated from the engine at the mounting flange. The airplane was removed to Hagerstown, Maryland, for further examination. The examination included manually rotating the crankshaft, which resulted in operation of the accessory gear drives, pistons, and valve operating mechanisms. Compression of each cylinder was confirmed; however, when a cold differential compression test was done the following results were obtained: #1 cylinder-- 54/80 (leak at intake valve) #2 cylinder-- 18/80 (leak past rings) #3 cylinder-- 62/80 #4 cylinder-- 66/80 This report was amended on July 29, 2004. ## Aircraft - Registration: [N93874](https://openairdocs.org/deregistered/N93874-1996-07-12), registration cancelled 1996-07-12, S/N 15285566 (OpenAirDocs) - Reported make and model: CESSNA 152 - Registry model: [Cessna 152](https://openairdocs.org/model/cessna-152) (registry code 2071835) (OpenAirDocs) - Category: Airplane - Serial number: 15285566 - Airframe hours: 7937 - Engines: LYCOMING O-235-L2C 110 horsepower reciprocating - Damage: Destroyed - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal; Standard, Utility - Last inspection: 100 hour, March 22, 1995, 32 hours before - Departed: MTN, BALTIMORE, MD - Destination: W54, WESTMINSTER, MD ## Flight crew As NTSB recorded them.

Gradual power loss en route. Down to 1300 RPM force landed. Nosed over. Leaking intake valve and leaking ring. From the NTSB's public API. 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.
