# NTSB NYC99LA038: Beech BE-76, N42RR, Cincinnatti, OH, December 19, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: December 19, 1998, 14:30 local (19:30 UTC) - Place: Cincinnatti, OH - Coordinates: 39.110549, -84.420623 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.1105&lon=-84.4206&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report December 5, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 45491 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC99LA038 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/45491/pdf - Page: https://openairdocs.org/ntsb/NYC99LA038 ## Probable cause The flight instructor's delay in initiating remedial action. Factors include a wet runway, and the student's inability to maintain airplane directional control during a simulated, on-ground engine failure. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - aborted - airport facilities,runway/landing area condition - wet (contributing factor) - aircraft control - not maintained, dual student (contributing factor) - remedial action - delayed, pilot in command(cfi) (cause) - On ground/water encounter with terrain/water, takeoff - aborted ## Analysis The flight instructor was giving instruction to the private pilot in anticipation of a multi-engine flight test. It had rained earlier, and the runway was still wet. The instructor gave the private pilot a simulated engine failure during the takeoff roll. He allowed the airplane to accelerate, and pulled back the mixture to the left engine at approximately 30 knots. The airplane veered quickly to the left, about 30 degrees. The private pilot did not retard both throttles immediately, so the flight instructor advanced the mixture on the left engine; however, the corrective action was too late, and the airplane departed the runway. The flight instructor reduced the power, and the brakes were applied. The airplane continued through the wet grass, then ran into an elevated asphalt driveway at 10 to 15 knots. The nose gear collapsed, and the airframe was bent. ## Factual narrative On December 19, 1998, about 1430 Eastern Standard Time, a Beech BE-76 Duchess, N42RR, was substantially damaged during the takeoff roll at Cincinnati Municipal-Lunken Field (LUK), Cincinnati, Ohio. The certificated flight instructor and private pilot were uninjured. Visual meteorological conditions prevailed at the time of the accident. A round robin instrument flight plan was filed for the instructional flight, which was conducted under 14 CFR Part 91. According to the flight instructor, he was giving instruction to the private pilot in anticipation of a multi-engine flight test. It had rained earlier, and the runway was still wet. The instructor gave the private pilot a simulated engine failure during the takeoff roll. He allowed the airplane to accelerate, and pulled back the mixture to the left engine at approximately 30 knots. The airplane veered quickly to the left, about 30 degrees. The private pilot did not retard both throttles immediately, so the flight instructor advanced the mixture on the left engine; however, the corrective action was too late, and the airplane departed the runway. The flight instructor reduced the power, and the brakes were applied. The airplane continued through the wet grass, then ran into an elevated asphalt driveway at 10 to 15 knots. The nose gear collapsed, and the airframe was bent. ## Aircraft - Registration: [N42RR](https://openairdocs.org/aircraft/N42RR), registered now, S/N ME-84 (OpenAirDocs) - Reported make and model: Beech BE-76 - Registry model: [Beech 76](https://openairdocs.org/model/beech-76) (registry code 1153005) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: ME-84 - Airframe hours: 5622 - Engines: Lycoming O-360 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Norbert J.

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.
