Following an engine shutdown, a precautionary landing is usually performed with airport fire and rescue equipment positioned near the runway. The prompt landing is a precaution against the risk that another engine will fail later in the flight or that the engine failure that has already occurred may have caused or been caused by other as-yet unknown damage or malfunction of aircraft systems ...
Lubrication is by use of pre-mixed fuel and oil at 50:1 or oil injection. The 618 has dual Ducati capacitor discharge ignition systems and is equipped with two piston-type carburetors. It uses a manifold-driven pneumatic fuel pump to provide fuel pressure. [1] The engine's propeller drive is via a Rotax type C or E style gearbox.
PRICE Systems’ cost estimating software was first developed in the 1970s when David Shore, a vice president in RCA's Government Group discovered that Frank Freiman, in the purchasing department, was able to predict the cost of military new systems with considerable accuracy before design was completed and a parts breakdown was available for ...
graph with an example of steps in a failure mode and effects analysis. Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects.
Overspeed is a condition in which an engine is allowed or forced to turn beyond its design limit. The consequences of running an engine too fast vary by engine type and model and depend upon several factors, the most important of which are the duration of the overspeed and the speed attained.

The engine is used on the A220, A320neo family, Embraer E-Jet E2 and the Russian Yakovlev MC-21 (although exports were stopped as part of the international sanctions during the Russian invasion of Ukraine). The Pratt & Whitney PW1000G engine family initially garnered significant interest from airlines due to its touted fuel efficiency advantages.
The 1965 guidance in AC 33-1 noted the favorability of "puncture resistant rotor housings or separate armor adequate to contain broken rotor blades and stator vanes" and engine rotor and bearings strong enough "to provide a strength margin for a period of shutdown and low speed windmilling when large unbalances typical of damaged rotor blading ...
