Cessna Aircraft Company 150, 152, 172, 177, 180, 182, 185, 188, 206, 207, 210, and 337 Series Airplanes

Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (f) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD) that applies to Cessna Aircraft Company (Cessna) 150, 152, 172, 177, 180, 182, 185, 188, 206, 207, 210, and 337 series airplanes. This AD requires measuring the visible length of standpipe (tube) in the top assembly of the fuel strainer assembly for the correct length, and replacing any fuel strainer assembly that does not have the correct length of standpipe. This AD is the result of reports that the fuel strainer assemblies on the affected airplanes were manufactured with the fuel standpipes incorrectly installed in the assembly housing top. The actions specified by this AD are intended to prevent foreign material from entering the fuel system and engine, which could result in loss of engine power or complete engine stoppage during flight.
To prevent foreign material from entering the fuel system and engine, which could result in loss of engine power or complete engine stoppage during flight, accomplish the following:
Note 2: This AD allows the aircraft owner or pilot to check the maintenance records to determine whether a Cessna part number (P/N) 0756005-2 top assembly, Cessna P/N 0756005-8 fuel strainer assembly, or a Cessna P/N 0756005-9 fuel strainer assembly was installed after December 12, 1996. Those parts that were shipped between December 12, 1996, and September 5, 1997, may have been manufactured with an internal tube installed to a depth less than specified and may become loose and dislodge from the strainer top assembly. See paragraph (c) of this AD for authorization.
(a) Within the next 12 calendar months after the effective date of this AD, unless already accomplished, measure the standpipe in the fuel strainer assembly (tube in the filter strainer top assembly) for a visible maximum length of 1.68 inches, in accordance with the ACCOMPLISHMENT INSTRUCTIONS section and Detail A in Cessna Single Engine Service Bulletin (SB) No. SEB97-9, dated November 17, 1997; or Cessna Multi-engine SB No. MEB97-12, dated November 17, 1997, whichever is applicable.
(b) If the standpipe does not measure a maximum length of 1.68 inches, prior to further flight, replace the filter strainer top assembly in accordance with the ACCOMPLISHMENT INSTRUCTIONS section in Cessna Single Engine SB No. SEB97-9, dated November 17, 1997; or Cessna Multi-engine SB No. MEB97-12, dated November 17, 1997, whichever is applicable.
(c) The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may check the maintenance records to determine whether a Cessna part number (P/N) 0756005-2 top assembly, Cessna P/N 0756005-8 fuel strainer assembly, or a Cessna P/N 0756005-9 fuel strainer assembly was installed after December 12, 1996. Those parts that were shipped between December 12, 1996, and September 5, 1997, may have been manufactured with an internal tube installed to a depth less than specified and may become loose and dislodge from the strainer top assembly. If, by checking the maintenance records, the owner/operator can make an absolute determination that one of these parts is not installed or was installed prior to December 12, 1996, the requirements of paragraphs (a) and (b) of this AD do not apply. The owner/operator must make an entry into the aircraft records showing compliance with this portion of the AD in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).
(d) As of the effective date of this AD, no person may install, on any of the affected Cessna airplanes, a fuel filter assembly where the maximum length of the standpipe does not measure 1.68 inches.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
