Citation Loss of Control Points to Pilot and Equipment Failures
Faulty angle-of-attack sensor identified in CJ upset incident.

A stuck angle of attack (AoA) sensor and the pilot's failure to monitor the flight instruments while climbing were factors in the Dec. 31, 2013 wing overstress accident involving a Cessna Citation CJ2+ after it departed controlled flight, according to a newly released report from the UK's Air Accidents Investigation Branch (AAIB). The light jet was being flown single pilot and departed from controlled flight just as it approached its assigned cruising altitude of FL430 over Coventry in central UK.
