NTSB Identification: ERA13LA288
14 CFR Part 91: General Aviation
Accident occurred Saturday, June 15, 2013 in Altoona, PA
Probable Cause Approval Date: 07/30/2014
Aircraft: HAGERTY RV-7A, registration: N954CH
Injuries: 2 Serious.
NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot reported that the airplane maintained 80 mph on final approach and slowed to 70 mph at touchdown. Upon touchdown on the main landing gear, the pilot reported that a wind gust occurred, and the airplane subsequently climbed and then landed hard on the nose landing gear, which bent under. The airplane then rolled off the runway onto grass and nosed over. The pilot reported no preimpact failure or malfunction that would have precluded normal operation. Both occupants reported having their lapbelts "snug" but not as tight as they could have been. Postaccident examination revealed that the nose landing gear was displaced and that a person's head with a similar sitting height as both occupants would have been about 1 inch below a crush line between the vertical stabilizer and the engine cowling. When the airplane inverted, both occupants struck their heads and sustained neck injuries that likely resulted from proximity of their heads to the canopy and might have been exacerbated by any slack in their restraints. Although postaccident measurements of the restraints confirm the occupants' statements that they were less than tight, anthropomorphic data for both occupants was not obtained, therefore; the amount of slack in either seat restraint was not conclusively determined.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's improper recovery from an encounter with a wind gust during landing, which resulted in a hard landing on, and displacement of, the nose landing gear and a subsequent runway excursion and noseover.
