The post-flight inspection revealed the regulator solenoid in the air turbine start control valve backed out of its housing, allowing uncontained bleed-air
to enter the start assembly.
He directed me to turn the personnel air conditioning switch to OFF, which also closed the fuselage bleed-air
While doing a special inspection on a E-2D, AD2 Luis Chonggarcia discovered a crack on the starboard, outboard bleed-air
The air flow in the venturi zone is regulated using a bypass air regulator, and a portion of the cleaning air is blown off through a bleed-air
valve at the back of the DeDuster to generate the necessary negative pressure at the DeDuster outlet.
The research is intended to result in the provision of on-board equipment to detect contaminants in engine and auxiliary power unit bleed-air
supplied to cockpits and cabins, and to filter out the contaminants.
The live-fire tests focused on dry bays that are located next to fuel tanks and spaces that house electrical and hydraulic lines, environmental control systems or engine bleed-air
The FE assessed aircraft bleed-air
, forced air cooling, and pressurization systems to determine cause of problem.
Compliance with bleed-air

The power-plant mechs opened up the 5th and 10th stage bleed-air
valves to inspect the compressor, and their worst fears were realized.
-leak-detection (BALD) system had commanded the bleed-air
valves to close, which shut off the bleed air leaking into the engine compartment.
I knew when a bleed-air
leak occurred the bleed-air
-leak-detection (BALD) system should shut it down, however; I didn't know the warning lights would go out so suddenly once the leak was isolated.
