(d) UNSAFE CONDITION
This AD was prompted by several reports of cracked engine exhaust
pipes. We are issuing this AD to prevent failure of the exhaust system
due to cracking, which could lead to uncontrolled engine fire, harmful
exhaust gases entering the cabin resulting in crew incapacitation, and
damage to the airplane.
(e) COMPLIANCE
Comply with this AD within the compliance times specified, unless
already done.
(1) For affected engines with an S/N listed in Figure 1 to paragraph (c)
of this AD with 400 hours or less time since new (TSN) or time since
last overhaul (TSLO), and for any TIO-540-AJ1A reciprocating engine
with a replacement turbocharger mounting bracket installed that was
purchased between April 5, 2012 and May 29, 2014, that has accumulated
400 hours or less time-in-service (TIS), within 25 hours after the
effective date of this AD, replace the turbocharger mounting bracket
with a part eligible for installation, and inspect the exhaust pipes
for cracks. Use Lycoming Engines Mandatory Service Bulletin (MSB) No.
614A, dated October 10, 2014, Exhaust System Disassembly and Removal,
paragraphs 1 through 22 to replace the bracket, and Exhaust System
Inspection, paragraphs 1 through 5 to do the inspection.
(2) For affected engines with an S/N listed in Figure 1 to paragraph (c)
of this AD with more than 400 hours TSN or TSLO, and for any TIO-540
-AJ1A reciprocating engine with a replacement turbocharger mounting
bracket installed that was purchased between April 5, 2012 and May 29,
2014, that has accumulated more than 400 hours TIS, replace the
turbocharger mounting bracket with a part eligible for installation,
and inspect the exhaust pipes for cracks at the next engine overhaul,
separation of the crankcase halves, or twelve years from the effective
date of this AD, whichever comes first. Use Lycoming Engines MSB No.
614A, dated October 10, 2014, Exhaust System Disassembly and Removal,
paragraphs 1 through 22 to replace the bracket, and Exhaust System
Inspection, paragraphs 1 through 5 to do the inspection.
(f) INSTALLATION PROHIBITION
After the effective date of this AD, do not return to service any TIO
-540-AJ1A engine with a turbocharger mounting bracket that was removed
from an engine identified in Figure 1 to paragraph (c) of this AD or
that was purchased between April 5, 2012 and May 29, 2014.
(g) CREDIT FOR PREVIOUS ACTION
(1) If, before the effective date of this AD, you replaced the turbo-
charger mounting bracket with one eligible for installation you may
take credit for your prior corrective action. No further turbocharger
mounting bracket replacement is required.
(2) If, before the effective date of this AD, you performed the crack in-
spection using either of the following:
(i) Lycoming Engines MSB No. 614A, dated October 10, 2014, Exhaust System
Inspection, paragraphs 1 through 5, or
(ii) Cessna Service Letter No. SEL-78-01, dated May 30, 2014, you may take
credit for your prior corrective action. No further inspection is re-
quired. However, you must still replace the turbocharger mounting
bracket.
(h) ALTERNATIVE METHODS OF COMPLIANCE (AMOCS)
The Manager, New York Aircraft Certification Office, FAA, may approve
AMOCs to this AD. Use the procedures found in 14 CFR 39.19 to make
