# NTSB SEA00LA077: PZL-Bielsko Jantar 2A, N272AS, Hood River, OR, April 22, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: April 22, 2000, 16:00 local (23:00 UTC) - Place: Hood River, OR - Coordinates: 45.610633, -121.580574 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=45.6106&lon=-121.5806&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report May 9, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49110 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA00LA077 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49110/pdf - Page: https://openairdocs.org/ntsb/SEA00LA077 ## Probable cause The pilot's failure to maintain directional control of the glider after its wing came in contact with long grass growing on the runway surface. Factors include the pilot's improper decision to attempt a landing on a runway with known directional control hazards, and long grass present on the runway surface. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Gear collapsed, landing - flare/touchdown - directional control - not maintained, pilot in command (cause) - in-flight planning/decision - improper, pilot in command (contributing factor) - airport facilities,runway/landing area condition - high vegetation (contributing factor) - landing gear - overload ## Analysis Upon arrival at the turf airstrip, the glider pilot noticed that the grass on the runway was significantly longer than normal, especially along the sides of the runway surface. During his first takeoff attempt, the right wing of his glider contacted the long grass, and it began to veer sharply to the right. At that point, the pilot released from the tow plane, and tried to maintain directional control as the glider came to a stop. Although he attempted to keep the aircraft aligned with the runway, the aircraft slid off the right side off the runway surface. After inspecting the glider for damage, and finding none, he attempted a second takeoff, which was successful. Upon returning to the airport after soaring for approximately four hours, the pilot elected to land on the same grass runway he had departed from, instead of on the adjacent paved runway. Although the touchdown was successful, at the very beginning of the landing roll, the wing again began contacting the long grass. Although the pilot tried to keep the aircraft tracking straight down the runway, the resistance of the grass pulling on the wing resulted in the aircraft turning sideways and sliding along the runway surface. As the aircraft slid, the gear collapsed and the fuselage fractured just aft of the wing trailing edge. ## Factual narrative On April 22, 2000, approximately 1600 Pacific daylight time, a PZL Jantar 2A glider, N272AS, experienced a gear collapse during a landing on the grass runway at Hood River Airport, Hood River, Oregon. The commercial pilot, who was the sole occupant, was not injured, but the aircraft, which was owned and operated by the pilot, sustained substantial damage. The 14 CFR Part 91 personal pleasure flight, which departed the same runway about four hours earlier, was being operated in visual meteorological conditions. No flight plan had been filed, and there was no report of an ELT activation. According to the pilot, on the day of the accident, he attempted to takeoff from the grass glider strip at the Hood River Airport. Prior to the takeoff, he noticed that the grass was longer than normal, especially near the sides of the runway. During the takeoff attempt, the right wing of the 20.5 meter glider began contacting the grass, and the aircraft started to veer off course. The pilot released from the tow plane and tried to maintain runway alignment, but the resistance of the grass against the wing resulted in the glider skidding off the right side of the runway. After coming to a stop, the pilot inspected the main landing gear for any damage that might have resulted from the sideloads encountered during the sudden change in ground roll direction. Finding no apparent damage, the pilot elected to attempt a second takeoff from the same runway. That takeoff was successful, and the pilot soared around the Mt. Hood area for nearly four hours. During the flight, the pilot extended and retracted the main gear, and found that the gear mechanism seemed stiffer than normal and that the wheel would not lock in the up position. Although he had no trouble getting the gear down and locked for landing, he thought that the wheel assembly might have sustained unseen damage during the aborted takeoff. According to the pilot, even though his wing had caught in the long vegetation during his first takeoff attempt on the grass runway, upon returning to the airport, he elected to land on the same grass strip instead of on the adjacent paved runway. He said that he elected to do so because he thought it was possible that the gear might collapse on touchdown and the aircraft's belly would slide on the asphalt surface. Although the touchdown on the grass strip was successful, during the initial part of the landing roll, the aircraft's wing again came in contact with the long grass. Although the pilot attempted to keep the aircraft tracking straight down the runway, the resistance of the grass pulling on the wing resulted in the aircraft turning sideways and sliding along the runway surface. As the aircraft slid down the runway, the main gear collapsed to the side and the fuselage fractured just aft of the wing trailing edge. ## Aircraft - Registration: [N272AS](https://openairdocs.org/aircraft/N272AS), registered now, S/N B-780, built 1976 (OpenAirDocs) - Reported make and model: PZL-Bielsko JANTAR 2A - Registry model: [Szybowcowy Zaklad Doswiadczaln JANTAR-2A-SZD 42-1](https://openairdocs.org/model/szybowcowy-zaklad-doswiadczaln-jantar-2a-szd-42-1) (registry code 8821640) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Glider - Serial number: B-780 - Airframe hours: 780 - Engines: unknown - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Gary D.
