# NTSB NYC95LA073: Beech 23, N9305S, Plymouth, NH, March 15, 1995 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: March 15, 1995, 17:25 local (22:25 UTC) - Place: Plymouth, NH - Location: 43.0374° N, 71.4699° W: Placed by OpenAirDocs at EVANS (NH12), within about a mile (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=43.0374&lon=-71.4699&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report July 31, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 38932 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC95LA073 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/38932/pdf - Page: https://openairdocs.org/ntsb/NYC95LA073 ## Probable cause THE PILOT'S FAILURE TO MAINTAIN RUNWAY ALIGNMENT DURING THE ABORTED TAKEOFF. FACTORS RELATED TO THE ACCIDENT WERE: THE ADVERSE RUNWAY CONDITIONS AND SNOWBANK BESIDE THE RUNWAY. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with terrain/water, takeoff - aborted - airport facilities,runway/landing area condition - soft (contributing factor) - airport facilities,runway/landing area condition - wet (contributing factor) - airport facilities,runway/landing area condition - snow covered (contributing factor) - lift-off - premature, pilot in command - aborted takeoff - performed, pilot in command - terrain condition - snowbank (contributing factor) - proper alignment - not maintained, pilot in command (cause) ## Analysis THE PILOT LANDED ON A SOFT/WET TURF RUNWAY THAT WAS NOTAMED TO HAVE PATCHY ICE AND SNOW. AFTER LANDING, HE TAXIED TO THE PARKING AREA. AFTER THE AIRPLANE WAS LOADED WITH 2 PASSENGERS AND LUGGAGE, THE PILOT INITIATED A TAKEOFF (USING SOFT FIELD PROCEDURES). JUST AFTER LIFT OFF (ABOUT 5 FEET ABOVE THE RUNWAY), THE STALL WARNING HORN SOUNDED, AND THE PILOT FELT THAT THE AIRSPEED WAS TOO LOW, SO HE DECIDED TO ABORT THE TAKEOFF. HE REPORTED THAT THE AIRPLANE WENT INTO A 'RIGHT BANK.' HE ATTEMPTED TO CORRECT BY APPLYING OPPOSITE AILERON AND RUDDER, BUT WAS NOT SUCCESSFUL. THE LEFT MAIN LANDING GEAR STRUCK A SNOW BANK ON THE RIGHT SIDE OF THE AIRSTRIP, AND THE AIRPLANE 'YAWED LEFT (AND) SETTLED TO THE GROUND, SKIDDING SIDEWAYS.' ## Factual narrative On March 15, 1995, at 1725 eastern standard time, a Beech 23, N9305S, piloted by Andrew Bonney, was substantially damaged after an aborted takeoff at the Plymouth Airport, Plymouth, New Hampshire. The pilot and the 2 passengers were not injured. Visual meteorological conditions prevailed and no flight plan had been filed for the flight operating under 14 CFR 91. On takeoff, at about 5 feet above the runway, the pilot felt that the airspeed was too low, and he aborted the takeoff. According to the pilot's written statement on the NTSB Form 6120.1/2, after making a pre-flight check and run up, he started his takeoff roll on a soft wet grass runway. He wrote: ...I applied full throttle, yoke full aft...softness slowed the aircraft's acceleration occasionally...I eased back pressure on yoke to keep nose off ground as speed re-eased...airspeed indicator showed insufficient airspeed to take-off at mid-point on runway...stall warning horn sounded...aircraft took low flight over each roll in strip, then settled to ground...I retarded the throttle to abort take-off.... The pilot wrote that the airplane went into a "right bank." The pilot attempted to correct by applying opposite aileron and rudder but was not successful. The left main landing gear struck a snow bank on the right side of the airstrip, "yawed left," and "settled to the ground, skidding sideways." ## Aircraft - Registration: [N9305S](https://openairdocs.org/deregistered/N9305S-1995-06-20), registration cancelled 1995-06-20, S/N M1632 (OpenAirDocs) - Reported make and model: BEECH 23 - Registry model: [Beech C23](https://openairdocs.org/model/beech-c23) (registry code 1151242) (OpenAirDocs) - Category: Airplane - Serial number: M-1632 - Airframe hours: 3628 - Engines: LYCOMING O-360-A3K 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: General Avation Service - Registered owner: Arthur 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.
