# NTSB FTW98LA312: Piper PA-30, N444BP, Watkins, CO, July 16, 1998 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: July 15, 1998, 21:45 local (Jul 16, 1998, 03:45 UTC) - Place: Watkins, CO - Coordinates: 39.749046, -104.60012 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.7490&lon=-104.6001&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor, 2 uninjured - Status: Completed, report June 21, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 43166 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW98LA312 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/43166/pdf - Page: https://openairdocs.org/ntsb/FTW98LA312 ## Probable cause The pilot misjudged his altitude. Contributing to the accident were unfavorable wind and dark night conditions. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Undershoot, approach - vfr pattern - final approach - weather condition - unfavorable wind (cause) - altitude/clearance - misjudged, pilot in command (cause) - light condition - dark night (cause) - In flight collision with terrain/water, approach - vfr pattern - final approach - terrain condition - open field ## Analysis Following takeoff for a local area personal night flight, the pilot noticed lightning to the north of his position so he returned to land. While on a 2 mile final for landing on runway 8, the aircraft settled and struck the ground. The pilot said he thought he encountered a low level wind shear. Weather at the time was scattered clouds with 10 miles visibility and wind from 160 degrees at 18 knots. An airport located approximately 7 miles northwest of the accident site was equipped with low level wind shear alert equipment which was operational. The equipment did not sound an alarm. The pilot said he was flying at 6,000 feet msl and the accident site elevation was 5,689 feet msl. ## Factual narrative On July 15, 1998, at 2145 mountain daylight time, a Piper PA-30, N444BP, sustained substantial damage when it impacted terrain during approach approximately 2 miles from the approach end of runway 8 at Front Range Airport, Watkins, Colorado. The airline transport certificated pilot and one passenger were not injured and the other passenger received minor injuries. No flight plan was filed for this local area personal flight which departed Front Range Airport at 2130. Visual meteorological conditions prevailed. According to the pilot, he encountered a low level wind shear and the aircraft was forced onto the ground. In his written statement and interview, the pilot indicated he saw lightning to the north after takeoff and proceeded to a downwind to land on runway 8. He said he was at "6,000 feet and 105 IAS" when he felt the airplane "sink." According to his statement, the aircraft lurched and decelerated as it contacted the ground. Elevation at the accident site was 5,689 above mean sea level. The closest weather reporting stations were Denver International Airport (DIA), located approximately 7 miles northwest of the accident site, and Front Range Airport (FTG), located approximately 3 miles east of the accident site were the same. According to their 2140 observations, there was scattered clouds at 11,000 feet, no ceiling and no precipitation. Visibility was 10 statute miles and the altimeter setting was 30.43 inches of mercury. Temperature was 68 degrees, dew point was 50 degrees and the wind was from 160 degrees magnetic heading at 18 knots. Lighting conditions were a dark night. The low level wind shear alert system was operational at DIA and there were no alerts during the time period of the accident. Density altitude was 7,300. The National Weather Service Doppler radar antenna site is located at Front Range Airport. According to their data, the antenna site is too close to the accident site to record meaningful information regarding wind activity. The pilot said that following the accident, he and his passengers walked to Front Range Airport where the injured passenger was transported by private vehicle to a local hospital for treatment. ## Aircraft - Registration: [N444BP](https://openairdocs.org/deregistered/N444BP-2012-09-10), registration cancelled 2012-09-10, S/N 30-1757, built 1969 (OpenAirDocs) - Reported make and model: Piper PA-30 - Registry model: [Piper PA-30](https://openairdocs.org/model/piper-pa-30) (registry code 7103002) (OpenAirDocs) - Registry engine: [Lycoming IO-320 series](https://openairdocs.org/engine/lycoming-io-320-series) (registry code 41509, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 1757 - Airframe hours: 3726 - Engines: Lycoming IO-320-B1A 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Arthur E.
