NOTE: See AD 2013-03-15 for complete instructions. These paragraphs are excerpts of the actual Airworthiness Directive and are intended for informational purposes only.
Effective March 19, 2013
Applies to specific serial numbered aircraft – See the AD.
SUMMARY: We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company Models 172R and 172S airplanes. This AD was prompted by reports of chafing of a new configuration of the fuel return line assembly, which was caused by the fuel return line assembly rubbing against the right steering tube assembly during rudder pedal actuation. This AD requires you to install the forward and aft fuel return line support clamps and brackets; inspect for a minimum clearance between the fuel return line assembly and the steering tube assembly and clearance between the fuel return line assembly and the airplane structure; and, if any damage is found, replace the fuel return line assembly. We are issuing this AD to correct the unsafe condition on these products
At whichever of the following compliance times that occurs later, inspect the fuel return line
assembly (Cessna part number (P/N) 0516031-1) for damage following the Accomplishment
Instructions section of Cessna Aircraft Company Service Bulletin SEB-28-01, dated September 21,
(1) At the next annual inspection after March 19, 2013 (the effective date of this AD);
(2) Within the next 100 hours time-in-service (TIS) after March 19, 2013 (the effective date of
this AD); or
(3) Within the next 12 calendar months after March 19, 2013 (the effective date of this AD).
