Summary
We propose to adopt a new airworthiness directive (AD) for certain Honeywell International Inc. (Honeywell) AS907-1-1A turbofan engines. This proposed AD was prompted by reports of loss of power due to failure of the second stage low-pressure turbine (LPT2) blade. This proposed AD would require a one-time inspection of the LPT2 blades and, if the blades fail the inspection, the replacement of the blades with a part eligible for installation. We are proposing this AD to correct the unsafe condition on these products.
