.
If the preparation of the external load by ground crew played a role, also code under RAMP.
.
Failures or malfunctions of the onboard external load handling lifting equipment or release systems should be coded under SCF-NP, as these are considered to be aircraft systems.
FIRE/SMOKE (NON-IMPACT) (F–NI)
.
Includes fire due to a combustive explosion from an accidental ignition source.
.
Includes fire and smoke from system/component failures/malfunctions in the cockpit, passenger cabin, or cargo area.
.
Non-combustive explosions such as tire burst and pressure bulkhead failures are coded under System/Component Failure – Non-Powerplant (SCF–NP).
.
Fire/Smoke resulting from an accident impact is coded under Fire/Smoke (post-impact) (F–POST).
FIRE/SMOKE (POST-IMPACT) (F–POST)
Fire/Smoke resulting from impact.
Usage Notes:
.
This category is only used for occurrences where post impact fire was a factor in the outcome.
.
This category is only used in conjunction with another category. For example, a system/component failure that also results in a post-impact fire will be coded as SCF–PP and F–POST or SCF–NP and F–POST.
FUEL RELATED (FUEL)
. The following fuel-related definitions are provided for clarity:
- Exhaustion: No usable fuel remains on the aircraft.
-Starvation/mismanagement: Usable fuel remains on the aircraft, but it is not available to the engines.
-Contamination: Any foreign substance (for example, water, oil, ice, dirt, sand, bugs) in the correct type of fuel for the given powerplant(s).
-Wrong fuel: Fuel supplied to the powerplant(s) is incorrect, for example, Jet A into a piston powerplant, 80 octane into a powerplant requiring 100 octane.
.
Includes cockpit crew or ground crew-induced fuel-related problems that are not the result of mechanical failures. Interruptions of the fuel supply caused by mechanical failures are coded elsewhere as non-powerplant or powerplant system/component failures (SCF–NP or SCF–PP), as appropriate.
.
Also used when the wrong fuel causes a powerplant failure (e.g., through detonation). In this case it should be coded as FUEL, not as a system/component failure or malfunction-powerplant (SCF–PP).
.
Includes cases where there was a high risk of fuel exhaustion but there was no actual loss of power.
GLIDER TOWING RELATED EVENTS (GTOW)
Premature release, inadvertent release or non-release during towing, entangling with towing, cable, loss of control, or impact into towing aircraft/winch. 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：AVIATION OCCURRENCE CATEGORIES DEFINITIONS AND USAGE NOTES(9)
