AD: Honda Aircraft Company LLC

AD NUMBER: 2018-21-13

PRODUCT: Certain Honda Aircraft Company LLC (Honda) Model HA-420 airplanes.

ACTION: Final Rule.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2018-11-05 for the aircraft listed above.

AD 2018-11-05 required incorporating a temporary revision into the airplane flight manual (AFM) and replacing the faulty power brake valve (PBV) upon condition.

AD 2018-11-05 was issued as a short-term action to address the immediate need to detect and replace a faulty PBV.

This AD retains the actions required in AD 2018-11-05 and requires replacing the faulty PBV with the improved part.

DATES: This AD is effective November 27, 2018.

COST: The FAA estimates that this AD affects 72 airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

  • Insert temporary revision into the AFM - 1 work-hour × $85 per hour = $85
  • Replace the power brake valve (PBV) - 20 work-hours × $85 per hour = $1,700. Parts - $21,878. Total cost per aircraft - $23,578.
