CF34 borescope inspection for regional jets

The GE CF34 powers the CRJ and Embraer E-Jet families in three main variants — -3, -8 and -10 — and the regional fleet changes hands often enough that its borescope inspections are a steady part of the transition business.

The variants

The -3 on the CRJ100/200, the -8 on the CRJ700/900/1000 and the E170/175, the -10 on the E190/195. Each has its own port map, limits and AMM; the method is the same.

What the inspection covers

Fan and booster for ingestion damage; the high-pressure compressor stage by stage; the combustor; the high-pressure and low-pressure turbines — recorded on video, findings sized against the CF34 limits, status per module.

Regional realities

Regional jets fly many short cycles, so cycle-driven wear and FOD from smaller airports show up more often than on long-haul engines. Scheduled inspections at line maintenance, unscheduled ones after ingestion events, and full transaction borescopes at lease events are the normal mix.

FAQ

Are CF34 borescope inspections shorter than on a narrowbody engine?
Usually; the engine is smaller, but the discipline and the report are the same.
Do lessors ask for video on regional engines?
Yes at transitions; the CF34 trades like any other engine.
Do you cover the CF34?
Tell us the variant, ESN and airport and we confirm capability.
