# NTSB NYC93LA181: Beech 19, N24685, Wolfboro, NH, August 31, 1993 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 31, 1993, 13:30 local (17:30 UTC) - Place: Wolfboro, NH - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report September 30, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 38653 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC93LA181 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/38653/pdf - Page: https://openairdocs.org/ntsb/NYC93LA181 ## Probable cause The pilot's failure to abort the takeoff which resulted in an overrun of the runway. Factors were a dirt bank, and the pilot's premature lift off, his failure to attain adequate airspeed, and his lack of recency of experience. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, takeoff - lift-off - premature, pilot in command - airspeed(vlof) - not attained, pilot in command (contributing factor) - lack of recent experience, pilot in command (contributing factor) - aborted takeoff - not performed, pilot in command (cause) ## Analysis THE PILOT WAS CONDUCTING A TAKEOFF ON RUNWAY 03. HE STATED THAT HE ROTATED THE AIRPLANE AT 45 MPH. THE AIRPLANE LIFTED OFF, BUT SETTLED BACK ONTO THE RUNWAY. THE AIRPLANE OVERRAN THE RUNWAY AND COLLIDED WITH A DIRT BANK. HE WAS ASKED IF THE NOSE HIGH ATTITUDE WAS HIGHER THAN USUAL AND HE REPLIED 'YES.' THE FAA STARTED AND RAN THE ENGINE WITH NO MALFUNCTIONS OBSERVED. THE PILOT REPORTED THAT HE HAD FLOWN 1.5 HOURS IN THE LAST 90 DAYS. ## Factual narrative On Tuesday, August 31, 1993, at 1330 eastern daylight time, a Beech BE-19, N24685, registered to K. R. Robinson, Inc., and piloted by Kendall A. Knox, sustained substantial damage during an attempted takeoff from the Lakes Regional Airport, Wolfboro, New Hampshire. The pilot and passenger were not injured. Visual meteorological conditions prevailed, and no flight plan was filed. The flight was being conducted under 14 CFR 91. The pilot initiated a takeoff on runway 30. In his report, the pilot stated: The aircraft accelerated to 45 mph and the nose- wheel came off the runway. The A/C continued to accelerate to 60 mph and the main gear came off the runway. The elevator was relaxed slightly in an attempt to accelerate in ground effect and avoid an imminent stall...however the aircraft settled back down onto the runway. The airspeed was between 55-60 mph and the A/C came off the runway again, but only briefly and again settled down failing to climb. At this point the A/C left the paved runway...through...piles of dirt... Mr. Thomas C. Schultz, Aviation Safety Inspector for the Federal Aviation Administration (Airworthiness), conducted an examination of the wreckage and an interview with the pilot. In his report, Mr. Schultz stated: The pilot stated that the run-up and power check were normal. When he attempted to take off...he lifted the nose at 45 MPH The aircraft lifted then settled back to the runway. He lowered the nose and accelerated to about 60 MPH, and lifted the nose again and the aircraft lifted then settled back again. ...the aircraft departed the end of the runway, hit some piles of dirt. His report continued: When asked if the nose high attitude was higher than usual he said YES. When asked if the aircraft just mushed forward down and off the end of the runway, he again said YES... Mr. Schultz's report also stated: On [October 1, 1993] an engine run was accomplished on the above engine while still attached to the fuselage....The engine was started with no difficulty.. ..No malfunction was found that could have caused the accident. The pilot reported that his total flight time within the 90 days prior to the accident was 1.5 hours. ## Aircraft - Registration: [N24685](https://openairdocs.org/deregistered/N24685-1996-07-12), registration cancelled 1996-07-12, S/N MB574 (OpenAirDocs) - Reported make and model: BEECH 19 - Registry model: [Beech B19](https://openairdocs.org/model/beech-b19) (registry code 1151215) (OpenAirDocs) - Category: Airplane - Serial number: MB-574 - Engines: LYCOMING O-320-E2B 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: K.
