No definition at this time.
Usage Notes:
• There are different types (categories) of multiple engine power loss:
- Environmental—An event initiating from essentially simultaneous power loss
from multiple propulsion systems for an environmental cause (e.g., bird, ice, rain,
hail, or volcanic ash ingestion).
- Maintenance—An event initiating from multiple propulsion system power loss
from clearly improper maintenance (e.g., failure to restore oil system integrity
after inspection).
- Other/unknown—An event initiating from multiple propulsion system powerloss
for reasons other than those characterized elsewhere, or where the initiating
event(s) are unknown. This includes unrelated events of engine powerloss within
the same flight.
OTHER ENGINE MALFUNCTION (SCF–PP–OTHEM)
An engine malfunction or abnormal behavior not specified elsewhere.
Usage Notes:
• None at this time.
PROPELLER AUTOFEATHER/PITCH LOCK (SCF–PP–PAPL)
Propeller system malfunction leading to inability to control the propeller.
Usage Notes:
• Control hunting is excluded as a normal product behavior.
Page Revised 9/2008 Page 7
PROPELLER SEPARATION/DEBRIS RELEASE (SCF–PP–PS)
Separation of single or multiple blades, large piece(s) thereof, or entire propeller.
Usage Notes:
• None at this time.
PROPULSION SYSTEM FIRE (SCF–PP–PSF)
A fire involving combustion external to the engine casings.
Usage Notes:
• This includes internal pylon fires, including events where fuel leaks from the pylon and
initiates a fire elsewhere.
• Propulsion system fires may be within fire zones or flammable fluid zones.
• Tailpipe fires, and hot air leaks resulting in fire warnings, without combustion, are excluded
from the definition and documented under “Tailpipe fire” or “Compartment overheat/air
leak”, respectively.
• Fires that remain internal to the engine casing are excluded.
• Grass, brush, or pooled fuel fires are also excluded.
PROPULSION SYSTEM FUME EVENT (SCF–PP–PSFE)
Significant smoke and/or fumes on the flight deck or cabin that are generated by the
propulsion system.
Usage Notes:
• None at this time.
Page Revised 9/2008 Page 8
RECIPROCATING ENGINE UNCONTAINMENT (SCF–PP–REU)
Engine debris that completely exits the engine compartment.
Usage Notes:
• None at this time.
REVERSER/BETA MALFUNCTION—FAILURE TO DEPLOY
(SCF–PP–RFD)
The failure of a thrust reverser to deploy or a propeller to enter beta mode
when commanded.
Usage Notes:
• None at this time.
REVERSER/BETA MALFUNCTION—INFLIGHT DEPLOY
(SCF–PP–RMID)
