Issue number: AO-2020-010-SI-02
Issue owner: United States Federal Aviation Administration
Transport function: Aviation: Air transport
Background: Investigation Report AO-2020-010
Issue release date: 08 July 2021
Current issue status: Open – Safety action pending

Safety issue description

Cessna 206 aircraft that feature a rear double cargo door do not meet the aircraft certification basis for the design of cabin exits. Wing flap extensions beyond 10° will block the forward portion of the rear double cargo door, significantly hampering emergency egress. This has previously resulted in fatalities.

Safety recommendation

Action number: AO-2020-010-SR-019
Action organisation: United States Federal Aviation Administration
Date: 08 July 2021
Action status: Released

The United States Federal Aviation Administration (FAA) advised that they had no comment on any aspect of the draft report and did not provide detail of any safety action related to the identified safety issue. Consequently, the ATSB recommends that the FAA takes safety action to address the certification basis for the design of the cabin doors in the Cessna 206, as wing flap extension beyond 10° will block the forward portion of the rear double door, significantly hampering emergency egress.
