The pilot stated that from his airplane’s parking place he could see two signs marking the runway but could not see the pile of gravel between the two signs because it blended with the terrain. The pilot reported that he began his takeoff roll from the gravel parking area, but had not yet reached takeoff speed, when the airplane collided with the pile of gravel, substantially damaging the left wing, firewall and engine mounts. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that a large pile of gravel had been left on the parking area that was close to the start of the runway. This pile was not in line with the starting point of the runway, but close to it. From where the pilot had his airplane parked he could see the two signs marking the runway and directly in the center was the pile of gravel that blended into the terrain. The pilot reported that he began his takeoff roll from this gravel parking area and collided with the pile of gravel at full power, but not yet takeoff speed. The left wing, firewall and engine mounts were substantially damaged. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N2701F](https://openairdocs.org/deregistered/N2701F-2012-07-23), registration cancelled 2012-07-23, S/N 18256801, built 1965 (OpenAirDocs) - Reported make and model: CESSNA 182J - Registry model: [Cessna 182J](https://openairdocs.org/model/cessna-182j) (registry code 2072722) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18256801 - Engines: CONT MOTOR O-470 SERIES 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Cravens G Ralph - Registered owner: Cravens G Ralph - Airworthiness certificate: Standard, Normal - Departed: U42, West Jordan, UT - Destination: Delle, UT - Airport: N/A, Delle, runway 25, 1,502 × 35 ft, gravel ## Flight crew As NTSB recorded them.
