Engine MountingEngine Mounting Most of the wreckage is from the aircraft wings. The centre sections of the port wing and starboard wing are fully preserved and lying upside down on the seabed. Most of the wings are still covered with the aluminium outer skin, though this skin is missing along the leading edges.
Engine BlockEngine Block Further wreckage between and to the north of the wing sections could be from the outer wing panels or the fuselage.
The four Pratt & Whitney R-1830 Twin Wasp engines are in situ on the wings though their cowlings are missing. The engine mount assemblies are still attached to the rear of the engines. The inboard and outboard engine mount supports have collapsed onto the underside of the wings.
The engine blocks with their 14 twin row cylinders are surrounded by the exhaust collector rings. The cylinders are 15cm in diameter.
Turbo SuperchargersTurbo Superchargers Each of the engines is associated with a rectangular Harrison or Airsearch flattened tube intercooler. The intercoolers serve to cool the hot compressed air delivered by the superchargers.
PropellerPropeller They are situated behind the firewall at the back of each engine. Loose Type B-2 turbosuperchargers were observed on the seabed in the vicinity of Engine 1 and Engine 2. The superchargers were originally located below and at the rear of the engines.
A round oil tank was observed to the east of Engine 1.
Engine 1 and Engine 2 both have hydromatic propellers. On Engine 1, the propeller is lying upside down with the dome buried in the seabed and the nose section facing upwards. The propeller on Engine 2 is lying upright on the seabed south of the engine with the dome facing west and the nose section facing east.
