The actions of a pilot-rated-passenger likely caused a dual engine flame-out of a Premier I business jet, according to factual information released by the NTSB.
On March 17, 2013, a Hawker Beechcraft 390 Premier IA business jet departed Tulsa, Oklahoma, on a flight to South Bend, Indiana. Three passengers and one pilot were on board. One of the passengers, a pilot, occupied the right hand seat in the cockpit. The pilot-rated passenger had accumulated 1,576 hours in multi-engine airplanes and 301 hours in single-engine airplanes. He had no experience in turbine-powered business jets.
Factual information released by the NTSB suggest that the pilot-rated passenger was allowed to fly the descent under supervision of the captain. During the descent the captain instructed the passenger to “just pull the power out” in order to slow the airplane down. Apparently the passenger lifted the pull-up locks on the throttles and retarded the throttles beyond flight idle, into the fuel cut-off position. The pilot told the pilot-rated-passenger “you went back behind the stops and we lost power.” During the approach the pilot was able to restart engine number 1.
However, the landing gear was not fully extended and the pilot carried out a go-around. The accident airplane was then observed to climb and enter a right traffic pattern for runway 9R. The airplane made another landing approach to runway 9R with only the nose landing gear extended. Several witnesses observed the airplane bounce several times on the runway before it ultimately entered a climbing right turn. The airplane was then observed to enter a nose low descent into a nearby residential community.
The airplane came down in a street, crashing into a house. Both persons in the cockpit were killed. Both passengers in the main cabin survived with serious injuries.
