SERVICE LETTER NO. 1261 ATA/JASC: 3418 SUBJECT: STALL WARNING HEAT CONTROL INSPECTION MODELS AFFECTED: SERIAL NUMBERS AFFECTED:

PA-46-350P Mirage 4622001 through 4622210; 4636001 through 4636459;

4636461 through 4636481 PA-46-500TP Meridian/M500 4697001 and up PA-46R-350T Matrix 4692001 through 4692153 COMPLIANCE TIME: Compliance is required whenever a wing salvaged from another aircraft has been installed.

APPROVAL: The engineering aspects of this service document have been shown to comply with the applicable Federal Aviation Regulations and are FAA approved.

PURPOSE: Piper Service Bulletin 1192 (and the associated FAA Airworthiness Directive, AD 2008-26-11) mandates a modification of the stall warning heat control system on some of the affected aircraft. For the remaining affected aircraft, this modification has been incorporated into production.

However, a salvaged wing that has been installed as a replacement may not have the required stall warning heat control configuration. This service letter provides instructions to identify and correct nonconforming stall warning heat control systems.

SAFETY INTENT: The safety intent of this service letter is to ensure that wiring for the stall warning heat control system meets current type design. If this wiring does not meet type design, it could result in no stall warning indication, in icing conditions, with the landing gear in the down position.

SERVICE LETTER NO. 1261 PAGE 2 of 6 INSTRUCTIONS:

NOTE: Some steps in these instructions are identified as “required for compliance” (RC). If this service letter is mandated by an airworthiness directive (AD), the steps identified as RC must be done to comply with the AD. Steps not identified as RC are recommended and may be deviated from, done as a part of other actions, or done with accepted methods different from those given in this service letter, if the RC steps can be done and the airplane can be put back in a serviceable condition.

NOTE: Wings, wing carry-throughs, and their attaching structure all have a structural life limit that is mandated by the FAA. The accumulated time in service (TIS) of a salvaged wing at the time of installation must be recorded in the airplane’s logbook, so that its remaining service life can be documented. Refer to Section 4-00-00 of the applicable Piper Airplane Maintenance Manual for published life limits. If the accumulated TIS of a salvaged wing is unknown, then its installation is not authorized.

NOTE: The following aircraft must be made compliant with SB 1192 (and the associated FAA Airworthiness Directive AD 2008-26-11), prior to accomplishing these instructions:

• PA-46-350P Mirage 4622001 through 4622210; 4636001 through 4636445

• PA-46-500TP Meridian 4697001 through 4697365

• PA-46R-350T Matrix 4692001 through 4692054 If Kit – Stall Warning Heat Control Modification, Piper part number (P/N) 88452-002, was previously installed on an aircraft’s current wings, in compliance with SB 1192, then the aircraft is exempt from this inspection.

NOTE: The aircraft that are affected by Piper Special Advisory 46-20, latest revision, must be made compliant with that document prior to accomplishing these instructions.

1. RC – Review the aircraft logbooks and/or maintenance records to determine if a wing has ever been replaced with a different wing, or a portion of a wing, which was salvaged from another aircraft.

• Inspection is not required if:

• The aircraft is required to be, and was made compliant with, SB 1192.

• The aircraft’s wings are original to the aircraft and it is not required to be made complaint with SB 1192.

• The aircraft’s replacement wings were obtained directly from Piper.

If no inspection is required, proceed to Step 4.

• Inspection is required if: the wings have been replaced with salvaged wings, or the service history of the aircraft is not fully known. Proceed to Step 2.

2. Gain access to the aft side of the left main wing spar through the main landing gear wheel well.

3. RC – Compare the stall warning heat control configuration to what is shown in Figure 1.

• No modification is required if the aircraft configuration matches View A–A and the associated wiring diagram. Proceed to Step 4.

• Modification is required if the aircraft configuration matches View B–B and the associated wiring diagram, or any configuration other than View A–A. Order and install Kit – Stall Warning Heat Control Modification, Piper P/N 88452-002. Then, proceed to Step 4.

4. Make a logbook entry documenting compliance with this service letter.
