Plain English Summary

3/10 complexity

This instrument adopts FAA Airworthiness Directive 91-18-10 for certain brake assemblies on Boeing 767s, imposing lower maximum wear limits and mandating the FAA’s inspection/repair actions. It affects owners, operators and maintenance providers of those 767s, shifting when brakes must be measured, repaired or replaced. The rule (with an Australian effective date of 12 Jan 1991) tightens safety margins after a rejected‑takeoff incident, increasing inspection burden, parts use and maintenance costs.

AD/B767/60 Brake Wear Limit 1/92

Applicability: Model 767 series, equipped with brake part number identified in paragraph (a) of the requirement document.

Requirement: Action in accordance with the technical requirements of FAA AD 91-18-10 Amdt 39- 8013.

Compliance: As specified in the requirement document, with a revised effective date of 12 January 1991 for Australian Registered Aircraft.

Background: An investigation by the FAA of a runway excursion by a transport category aircraft following a rejected takeoff, has revealed that the majority of brake assemblies were neat the current maximum wear limit and unable to absorb the required takeoff energy. This Directive requires new maximum brake wear limits. The effective date required by the FAA is extended by two months.
