Plain English Summary

2/10 complexity

Requires inspection of Brackett BA-2410 engine air filters on Cessna TP206/TU206 aircraft and, where the element has only one grill screen, mandates installation of an additional grill screen (P/N 2404-00) at the next access or scheduled inspection (Requirement; Applicability; Compliance). Applies only where the original Cessna filter was replaced by the Brackett unit; CASA issued the change after an NTSB finding about single‑screen ingestion risk—owners/operators bear inspection and installation costs (Applicability; Background).

Amdt 1

Brackett Engine Air Filters 5/2003

Applicability: Cessna TP206 and TU206 series aircraft incorporating a Brackett Aero Filters Inc. engine air inlet filter Part Number (P/N) BA-2410.

Note 1: Brackett air filters are an approved alternative to the original Cessna air filter. This Directive is only applicable to aircraft that have had the original Cessna air filter replaced by a Brackett air filter.

Requirement: Inspect the engine air filter element for correct installation. If the filter has only one grill screen, install an additional grill screen P/N 2404-00.

Note 2: The BA-2410 filter element was revised in 1993 to have a screen on both faces of the filter.

Note 3: FAA AD 2002-26-03 refers.

Compliance: Effective 15 May 2003; unless previously accomplished; at next access to the engine air filter or next scheduled aircraft periodic inspection, whichever occurs first.

This amendment becomes effective on 15 May 2003.

Background: This Directive was originally issued to require an inspection of Brackett engine air inlet filters to ensure the filter has been installed correctly. The requirement reflects the NTSB investigation of a fatal Cessna T210 accident disclosed the single grill screen had been installed incorrectly allowing the filter element to be ingested. This amendment requires a second screen to be installed on all applicable Brackett air filter installations.

The original issue of this Airworthiness Directive became effective on 11 July 2002.
