Federal Register 2010-28579 · Final rule; correction
The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to the products listed above. In the Information Heading and in the SUMMARY section of the published AD, we incorrectly included Cessna 188 series airplanes. In the Unsafe Condition section, we incorrectly designated that paragraph as (e) instead of (d). Also in the Compliance section, paragraph (f)(2), and in Figure 1, we incorrectly stated the mailing address for the report. We are issuing this document to help eliminate any confusion that this AD may have created in the Information Heading and in the SUMMARY and Unsafe Condition sections. This document corrects those errors. In all other respects, the original document remains the same.
A correction restates part of an AD that was published incorrectly. It is
not an additional requirement and it does not change the AD number or its effective date.

The FAA is adopting a new airworthiness directive (AD) to supersede AD 2006-17-04, which applies to certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182T, T182T, 206H, and T206H airplanes. AD 2006-17-04 currently requires you to inspect the two end fittings on each of the flexible fuel hoses located in the engine compartment for the correct torque values, and, if any incorrect torque values are found during the inspection, tighten the hose end fittings to the correct torque values. This AD results from four reports of loose fuel lines connected to the fuel servo or fuel flow transducer. Two reports were of in-flight engine failure on a Model T182T airplane. A third report was of in-flight engine failure on a Model 206H airplane. A fourth report was of a Model 172S airplane losing engine power on final approach. Consequently, this AD would require you to establish the correct torque values of the end fittings on fuel hoses for certain Cessna Models 172R, 172S, 182T, T182T, 206H, and T206H airplanes. This AD clarifies that the torque values need to be physically established and visual inspection only is not sufficient. We are issuing this AD to detect and correct potential loss of fuel flow, which may result in partial or complete loss of engine power and/or uncontrolled engine compartment fire due to fuel leakage forward of the firewall.

This AD requires you to install Modification Kit MK172-25-10C or a steel lock rod/bar on both crew seat back cylinder lock assemblies. If a steel lock rod/bar has already been installed on the crew seat back cylinder lock assembly, no further action is required. If you have already installed Modification Kit MK172-25-10A or MK172-25-10B, this AD requires you to do an installation inspection and correct any discrepancies found. This AD results from reports of the crew seat back cylinder lock assembly failing at the aft end and other cylinder lock assemblies found cracked. We are issuing this AD to prevent the crew seat back cylinder lock assembly from bending, cracking, or failing. This failure could cause uncontrolled movement of the seat back, resulting in possible backward collapse during flight. Backward collapse of either crew seat back could result in an abrupt pitch-up if the affected crew member continues to hold on to the control yoke during this failure and could cause difficulty in exiting the airplane from an aft passenger seat after landing.

Requires you to inspect and, if necessary, modify the pilot/co-pilot upper shoulder harness adjusters that have certain Cessna accessory kits incorporated.
The FAA adopts a new airworthiness directive (AD) that will supersede AD 86-26-04, which applies to certain Cessna Aircraft Company (Cessna) 120, 140, 140A, 150, F150, 170, 172, F172, FR172, P172D, 175, 177, 180, 182, 185, A185E, 190, 195, 205, 205A, 206, P206, P206E, TP206A, TU206, TU206E, U206, U206E, 207, T207, 210, T210, 336, 337, and T337 series airplanes. AD 86-26-04 currently requires you to inspect and, if necessary, modify the pilot/co-pilot upper shoulder harness adjusters that have certain Cessna accessory kits incorporated. This AD is the result of reports that additional airplanes have the same unsafe condition and the manufacturer revised the service information to add these airplanes and correct the part number of the shoulder harness adjusters. Consequently, this AD retains the actions of 86-26-04, adds additional airplanes to the applicability section of this AD, and incorporates the revised service information. We are issuing this AD to prevent slippage of the pilot/co-pilot shoulder harness, which could result in failure of the shoulder harness to maintain proper belt length adjustment and tension. Such failure could result in pilot/co- pilot injury.

This document makes a correction to Airworthiness Directive (AD) 2003-24-13, which was published in the Federal Register on December 4, 2003 (68 FR 67789), and applies to certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes that are equipped with a Honeywell KAP 140 autopilot computer system installed on the center instrument control panel near the throttle. We inadvertently duplicated affected airplane serial numbers and included a serial number that should not be affected by this AD in the applicability section. This action corrects the applicability section of AD 2003-24-13, Amendment 39-13382.
A correction restates part of an AD that was published incorrectly. It is
not an additional requirement and it does not change the AD number or its effective date.

Airworthiness Directives; Cessna Aircraft Company Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H Airplanes
The FAA supersedes Airworthiness Directive (AD) 2003-24-13, which applies to certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes that are equipped with a certain Honeywell KAP 140 autopilot computer system installed on the center instrument control panel near the throttle. AD 2003-24-13 currently requires you to install an update to the operating software of certain KAP 140 autopilot computer system, change the unit's part number, and change the software modification identification tab. This AD is the result of the FAA inadvertently omitting four affected Honeywell KAP 140 autopilot computer system part numbers and an affected airplane serial number from the applicability section of AD 2003-24-13. This AD retains the actions required in AD 2003-24-13, corrects the applicability section, and incorporates a revised installation bulletin issued by Honeywell.

Airworthiness Directives; Cessna Aircraft Company Model 182S Airplanes
This amendment adopts a new airworthiness directive (AD) that applies to all Cessna Aircraft Company (Cessna) Model 182S airplanes. This AD requires repetitively inspecting all engine exhaust muffler end plates (four total) for cracks and replacing any muffler where an end plate is found cracked. The AD also requires fabricating and installing a placard that specifies immediately inspecting all engine exhaust muffler end plates any time the engine backfires upon start-up. This AD is the result of incidents where cracks were found in an engine exhaust muffler end plate on several of the affected airplanes. These cracks were caused by high stresses imposed on the attachment of the exhaust at the area of the firewall. The actions specified by this AD are intended to detect and correct damage to the engine exhaust mufflers caused by such high stress and cracking, which could result in exhaust gases entering the airplane cabin with consequent crew and passenger injury.

Airworthiness Directives; Cessna Aircraft Company Model 182S Airplanes
This amendment supersedes Airworthiness Directive (AD) 98-13- 10, which currently requires repetitively inspecting all engine exhaust muffler end plates (four total) for cracks on all Cessna Aircraft Company (Cessna) Model 182S airplanes, and replacing any muffler where an end plate is found cracked. AD 98-13-10 also requires fabricating and installing a placard that specifies immediate inspection of all engine exhaust muffler end plates any time the engine backfires upon start-up. This AD is the result of Cessna developing an improved design exhaust system for the Model 182S airplanes. This AD retains the actions of AD 98-13-10 on all affected airplanes, and requires replacing the exhaust system with an improved design exhaust system within a certain period of time, as terminating action for those requirements retained from AD 98-13-10. This AD also limits the effectivity to exclude those airplanes manufactured with the improved design exhaust system. The actions specified by this AD are intended to detect and correct damage to the engine exhaust mufflers caused by cracking and the high stresses imposed on the attachment of the exhaust system at the area the firewall, which could result in exhaust gases entering the airplane cabin with consequent crew and passenger injury.

Airworthiness Directives; Cessna Aircraft Company 180, 182, and 185 Series Airplanes
This amendment adopts a new airworthiness directive (AD) that applies to all Cessna Aircraft Company (Cessna) 180, 182, and 185 series airplanes that have wing extension supplemental type certificate (STC) SA00276NY or supplemental type approval (STA) SA93-136 incorporated. This AD requires inspecting between wing station (W.S.) 90 and W.S. 110 for an angle stiffener at the lower wing spar splice. If the angle stiffener is not installed, this AD requires installing a reinforcing strap. This AD is the result of failed test results revealing that the wings of these Cessna airplanes, without the stiffener, do not meet the applicable design requirements after being modified by the above STC. The actions specified by this AD are intended to prevent wing failure during flight caused by the absence of an angle stiffener, which could cause loss of control of the airplane.

Airworthiness Directives; Cessna Aircraft Company Models 172R and 182S Airplanes
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 98-01-01, which was sent previously to all known U.S. owners and operators of certain Cessna Aircraft Company (Cessna) Models 172R and 182S airplanes. This AD requires fabricating and installing placards to prohibit operation in instrument flight rules (IFR) conditions and use of the alternate static air source; inspecting the alternate static air source valve to assure that the alternate static air source port is not restricted by the identification placard and to assure that the valve body does not separate from the valve flange; and reworking or replacing as necessary. The AD was the result of reports of improper installation of the identification placard on the alternate static air source. The actions specified by this AD are intended to prevent erroneous indications from the altimeter, airspeed, and vertical speed indicators, which could cause the pilot to react to incorrect flight information and possibly result in loss of control of the airplane.
