Company Publishes Updated Service Instruction To Its Online Knowledge Base

The FAA has granted Lycoming Engines a 200 hour extension to the TBO on certain engine models.

Lycoming requested a global Alternate Method of Compliance to AD 2010-19-01 from the FAA to allow operators to use the time periods specified in Lycoming SI 1009BA to define the time of the next overhaul. In a letter dated June 15, 2017, the FAA said it was approving the Global AMOC requested by the company.

However, "The new 200 hour extension introduced by SI 1009BA is only applicable to engines with "15" in the "See Note" column, and note 15 specifies that engines affected by, and not in compliance with, AD 2012-19-01 are not eligible for the 200 hour extension. All the notes addressing the TBO extension ... specify that any engine affected by, and not in compliance with AD 2012 19-01 are not eligible for the TBO extension. The 12 year calendar time limit currently in SI 1009 has not changed."

According to the new Service Instruction, the new section 15 states that the 200 hour extension to the listed TBO can be applied to Lycoming Factory New, Lycoming Factory Rebuilt, and Lycoming Factory Overhauled engine models. Engine repairs or field overhauls that are performed by any entity other than the Lycoming Factory in Williamsport PA must meet all of the following requirements to be eligible for this 200-hour TBO extension:
a. Be performed using ONLY Lycoming genuine parts or FAA-PMA parts approved by Lycoming
b. Be performed using ONLY Lycoming approved procedures
c. Block 12 of FAA form 8130-3 must indicate the repair or overhaul was performed using ONLY Lycoming approved procedures and Lycoming genuine parts or FAA-PMA parts approved by Lycoming

A repair or overhaul performed using any FAA approved local shop procedures or using FAA-PMA parts not approved by Lycoming is not eligible for this 200-hour TBO.
