Aircraft Bleed Air leak
- Is defined that are sourced from a Turbine engine, refers to the compressed air, taken from within the engine compressor stages before the combustors.
- Two Factors of Controlled bleed air, ‘High temperature (200 – 250 °C) & 'Moderate pressure' (approx. 40 Psi) is used for Engine start, air conditioning, pressurization, engine & airframe de/anti-icing.
- Aircraft ‘Bleed Air Leak’ is basically the 'uncontrolled loss' of bleed air from any part of the aircraft pneumatic system or from the applications of it.
- Damage to Aircraft Nacelles, Structures & Wirings.
- Components to overheat.
- Inflight fire.
- Cockpit Gauges.
- Overheat Detectors.
- Bleed Shut-off Valves.
- Bleed Monitoring Systems.
- Fire Wall Bleed Shut-off Valves.
- Even after bleed air leak has been secured using the AFM , ECAM or QRH inflight, degradation in the operation of other aircraft systems are inevitable.
- A Perfect Leak Check Using Approved methods of AMM is Vital to Upkeep the Airworthiness.
