APPROVAL: The technical contents of this Service Bulletin have been approved by the Federal Aviation Administration (F.A.A.). P U R P O S E : It has been discovered that existing induction air filters, Piper Part number 460-632 (as manufactured by Purolator under the name FACET), may exhibit a condition where the plastisol (black plastic ends) show signs of deterioration, exhibiting cracking, splitting and crumbling. The vendor, Purolator, has issued Service Bulletin SB090298.01 which addresses this condition. Left uncorrected, the aircraft engine may ingest pieces of the plastic material of unknown size which could lead to a reduction in power or engine stoppage. This Service Bulletin provides distribution of Purolator Service Bulletin, SB090298.01, which requires an inspection and possible replacement of the affected air filter. I N S T R U C T I O N S : 1. Read the attached Purolator Service Bulletin SB090298.01 and fully comply in conjunction with the instructions below. 2. If the affected air filter has not been installed or is being installed as a replacement and is new in the box, check the box label for the assembly date code marked as A1Q97 through A3Q98. If these date codes appear, return the air filters to the place of purchase. If already installed, continue with these instructions. Note: Defective air filters were produced from January 1997 through mid September 1998, however, it may be difficult to determine dates due to the lack of identification on the air filter. Air filters should be suspect unless a positive identification can be made. 3. Gain access to the air filter in your particular model aircraft. Refer to the appropriate chapter of the applicable Service/Maintenance Manual as required. 4. Remove the air filter and examine. If the air filter is identified as a brand other than FACET, proceed to instruction 7. If the air filter is identified as FACET p/n 638873 (white ink stamp) or if no identification can be found, continue with these instructions. 5. Referring to the Purolator Service Bulletin and our Figures 1 & 2, determine the condition of the air filter. If the air filter plastisol ends show signs of deterioration such as cracking, splitting, or crumbling, on either side, replace the air filter prior to the next flight. If there are no obvious signs of deterioration, and if the air filter is airworthy, perform the inspection as outlined in the Purolator Service Bulletin. Should the air filter pass this inspection, return the air filter to service for a period of time not to exceed twenty-five hours time in service. (See Compliance Time above.) 6. If the defective air filter has lost portions of the black plastisol material, it will be necessary to inspect the induction system for the loose particles and debris. Clean as required. Refer to the appropriate chapter of the applicable engine or airframe Service/Maintenance Manual as required. 7. Clean and inspect the air filter for condition. Reinstall the existing or new air filter as required. Do not install the existing air filter unless clean and in airworthy condition. Perform an engine ground run to check performance. If successful, reinstall panels, cowls etc. to return the aircraft to service. 8. Upon compliance with the Purolator Service Bulletin and completion of these instructions, make an appropriate logbook entry of compliance with this Service Bulletin.

CA161PL). The suspect air cleaners will be identified with a .250 (%) inch high (white) ink stamp “FACET - 638873” and may include “FAA-PMA”. It has been discovered that a number of air cleaners manufactured during the 1st quarter of 1997 through the 3rd quarter of 1998 may exhibit deterioration, cracking, splitting or crumbling of the plastisol (black plastic) ends. Purolator requests that immediately upon receipt of this bulletin, all applicable aircraft utilizing these parts be inspected as follows. Instructions: 1. Gain Access to the air cleaner. Refer to appropriate chapter of the applicable Service/Maintenance Manual as required. 2. Remove the air cleaner and examine. If the air cleaner is identified with .250 (%) inch high, (white ink stamped) characters “FACET - 638873” and in some instances “FAA-PMA” (Refer to Figure 2), examine the air cleaner’s plastisol (black rubber) ends for signs of deterioration including cracking, tearing or crumbling. Both ends, inside and outside diameters should be inspected (Refer to Figure 1). If air cleaner exhibits any signs of deterioration, replace immediately. If no signs of deterioration are found, air cleaner can be re-installed in accordance with applicable Service/Maintenance Manual, but must be replaced within the next 25 hours of operation. If the air cleaner is identified with .125 (X) inch high, (white ink stamped) characters “FACET - 638873” and in some instances “FAA-PMA” (Refer to Figure 2), filter is not suspect and is acceptable for continued use, proceed to step 4.

If the air cleaner is defective and has lost portions of the black plastisol material, it is necessary to inspect the induction system for loose particles and debris. Clean as required. Refer to the appropriate chapter of the applicable engine and airframe Service/Maintenance Manuals as required. 4. Upon the completion of the existing air cleaner identification and inspection and should the air cleaner be found to be in an acceptable condition, reinstall the air cleaner in accordance with the applicable Service/Maintenance Manual. 5. If a new Purolator/Facet air cleaner is being installed as a replacement, verify identification depicted in Step 2, Figure 2. Acceptable air cleaners will now include a six (6) digit, manufactured date code. The date code will reflect the “Month - Day - Year” the filter was manufactured. Some filters will also include “FAA-PMA”. 6. Upon the completion of this inspection and the return of aircraft to service, note compliance with this Service Bulletin in the aircraft logbook.
