Walked SE till dark and slept until dawn. Three of the crew joined me at this village. The fourth joined us at noon the next day. Natives carried us to Sian where a car took us into Chuchow. Six nights were spent at Army Air station there and on Saturday evening we left by train for Yun San. A bus met us and in this we traveled three days to Heng Yang. A plane met us there and brought us to Chunking.

SUBJECT: Report of Engineering on four airplanes.
TO: Chief of Air Corps -- Attn: Brig. Gen. Doolittle


Engines and accessories.

General engine performance was exceptionally good. Low rpm and high manifold pressures were used for long range cruise. Cylinder head temperatures were normal (170 ave). Oil temperatures remained well within the low range (normal).

Difficulties were confined to occasional starving of engine due to sudden load or quick increase of Hg. This was to be expected in auto lean position.

On board ship plug trouble was encountered during warm-ups. It was found the BG-LS-65 plug was superior to the AC-LS-85 (ceramic).

Corrosion was not excessive on engine or accessories. The largest amount being on the boiler in the left exhaust and the exposed sections of the cylinder barrel.

Recommendations.

BG-LS-plug (cold) be used under conditions where several run ups are required over a great period of time between flights.

Airplane General.

No difficulties of importance were encountered during mission.

Recommendations.

Special bomb bay tank was unsatisfactory in one case. The inner lining ruptured with result that the tank leaked in spite of all attempts to repair it.

Venting system of crawlway tank was satisfactory only under daylight conditions.
Bomb bay and turret tank vents could be placed so as to reduce the vacuum created by the airflow.


Corrosion of aileron, appendage and flap hanger bolts was excessive, special bolts needed.

Transfer pump should be placed in an accessible spot so that repair can be accomplished in flight.
