Applicability and Compliance

The AD schedule applies to various models of the Piper PA-32 series, including the PA-32-260, PA-32-300, PA-32-301T, PA-32R-300, PA-32R-301, PA-32R-301T, and PA-32S-300. Each AD specifies the applicable serial numbers and compliance deadlines, which range from immediate inspections to modifications required within specific flight hour limits.

Modification Requirements

Several modifications are mandated, such as the alternator regulator system modification (DCA/PA32/1) and the disc brake assembly modification (DCA/PA32/3). These modifications are critical for addressing identified safety issues and must be completed by specified compliance dates.

Inspection Protocols

The document outlines various inspection protocols, including the inspection of aileron cables (DCA/PA32/8) and fuel tanks (DCA/PA32/9A). Inspections are required before the next flight or within specified flight hours to ensure continued airworthiness.

Cancellation of ADs

Some ADs listed in the schedule have been cancelled, indicating that previous safety concerns have been addressed or are no longer applicable. For example, DCA/PA32/16 is marked as cancelled.

Links to Additional Resources

The document provides links to the FAA website for obtaining State of Design ADs and additional resources for compliance. This is essential for operators to stay updated on any new or amended directives.

Effective Date: 28 December 2020 * 2020-26-16 Wing Spars – Inspection Note 1: FAA AD 2020-26-16 uses a formula to determine when the aircraft was operated in flight training, or other high-load environments to determine the Factored Service Hours (FSH). This means that New Zealand aircraft affected by the FAA AD are only those aircraft operated at any time during their life by a commercial flight training organization, which would include an Aero Club, or a Flying School. The formula is based on the maintenance inspection requirements under Federal Aviation Regulations (FAR) 91.409(b), where a commercial aircraft used for hire must have 100-hour inspections, and an aircraft operated privately (i.e. not for hire) must have annual inspections. This distinction is not as easy to make in New Zealand, where Civil Aviation Rule (CAR) 91.605(c) requires that the manufacturer’s 100-hour inspection, or an equivalent inspection must be carried out every 12-months and therefore in New Zealand a 100-hour and a 12-month inspection are considered the same. To determine the number of 100-hour inspections (N) for the formula as required by FAA AD 2020-26-16, the CAA will accept counting all 12-month (annual) inspections carried out in accordance with CAR 91.605(c), as well as counting all 100-hour inspections carried out in any 12-month period, when the aircraft was operated by a commercial flight training organisation. (This would include an Aero Club, or a Flying School). If it cannot be determined with certainty who the operator of the aircraft was at the time of the 100-hour, or the 12-month (annual) inspection, then all the inspections must be counted in the number N. Piper PA-32 Series (Cherokee 6, Saratoga, Lance and Seaplane) Issued 28 January 2021 Page 21 of 21 CAA of NZ Note 2: The eddy current inspection mandated by paragraph (i) of FAA AD 2020-26-16 must be accomplished in accordance with the requirements in Rule 43.67 using an approved technique. Note 3: Notes and a compliance introduced to the AD to provide clarity regarding the determination of N in the formula as required by FAA AD 2020-26-16. Compliance: In accordance with FAA AD 2020-26-16, except that the operator may elect to use the aircraft hours TTIS as the Factored Service Hours (FSH) in lieu of a logbook review, or if the number of 100-hour inspections (N) when the aircraft was operated by a commercial flight training organization cannot be determined.
