We are currently selling a low time Walter GE M601-D11 that requires an overhaul. Logs present to 2007, approved maintenance to 2014. This engine is currently mounted to a Grumman Ag Cat. Engine run up video from November 2017.
TTSN: 5862.4, TBO: 146.4, Overhauls: 4
Last maintenance certificate: 05/06/2014.
Contact us to discuss IRAN / overhaul options, pricing and timings. The engine is available now and the owner is ideally looking for an M601-E11.
Background
Turbine engine reliability and performance has long been desired by, but rarely available to the general private pilot community. The Walter M601-B is an outstanding engine in its own right and until recently, was largely found on Let 410 passenger/cargo and Let 19 aerobatic aircraft.
The M601-B weighs just 197kg (418lbs). The recommended TBO for this engine is defined in engine start 'cycles, flight time and calendar time. Factory recommended TBO intervals vary from 2,250-20,000 cycles (depending on type of service and engine series), from 1,500-3,000 hours flight time, and from 5-8 years calendar time between overhauls. However, 300hr inspections are advisable.
For reference, even though the M601-B engine has been superceded and is no longer supported by Walter GE, it can still sell for around €25-30,000. Due to the high operational serviceability of these engines, overhauled units with limited remaining TBOs can be found to be in the €45,000-€50,000 range.
Log books are present and available for inspection.
Prices: from €25,000 +shipping (depending on which engine chosen).
See below for more information and contact us with your questions.
We are currently looking to acquire a GE Walter M601-E11 variant with a healthy TBO time remaining. Please get in touch with a sensible offer if you are interested in selling your unit. We are only interested in engines within calendar life and at least 500hrs TBO remaining. Current engine log book and maintenance certificate must be available.
Factory recommended TBO intervals vary from 2,250 to more than 20,000 cycles (depending on type of service and engine series), from 1,500-3,000 hours flight time, and from 5-8 years calendar time between overhauls. We recommend a complete IRAN engine reconditioning at 1,000 hour intervals, with periodic 300 hour inspections (oil change, filter/screen cleaning, compressor wash, bore scope inspection, etc.).
