# Have crash investigators ever used pilot cameras to help find the cause of a GA crash?

With video cameras being completely ubiquitous and GoPro cameras able to be mounted pretty much anywhere, lots of GA pilots now like to make videos of their own flights. A passenger's cell phone video was used as supporting evidence in the Germanwings crash. Have there been any situations so far where a GA crash has been puzzling to investigators until they watch the video from the pilot's camera which shows the cause clearly? Are they even allowed to do this (anywhere, but NTSB in particular) or are there privacy regulations which prevent them from doing so?

• Kind of related edition.cnn.com/2015/02/03/us/selfie-plane-crash NTSB used the footage to conclude that taking the footage [maybe] caused the crash. – ymb1 Jun 25 '16 at 1:11

• I remember this case where a passenger camcorder was used to determine the speed of the engines, and the fact that the pitch of the propellers was reversed in flight in the landing phase, causing the accident. A spectral analysis was conducted on the tape soundtrack. The accident happened in a Twin Otter at Saint Barth, a spectacular approach (note the windsock horizontal position at La Tourmente pass). – mins Jun 25 '16 at 13:15
