Program officials told the GAO that the event did not represent a typical operational scenario because the lawn was exposed to exhaust for longer than it would be under normal operating conditions. The GAO listed three candidate fixes then under study: changes to operational procedures, changes to the helicopter, and lawn surface treatments. Sikorsky flight-tested a prototype auxiliary power unit exhaust deflector in March 2020. The VH-92A is a derivative of the commercial S-92A, flown by Marine Helicopter Squadron One (HMX-1) alongside the VH-3D Sea King and VH-60N White Hawk it was bought to replace.
