**Buyer:** Federal Aviation Administration (FAA)
**Posted:** November 13, 2026
**Respond By:** December 28, 2026
**Identifier:** FAA-2026-13811

The FAA notice proposes aviation safety requirements for Pratt & Whitney Canada engines and certain Boeing 787-8 airplanes; it is not a procurement solicitation.
- Government buyer and action
  - U.S. Department of Transportation, Federal Aviation Administration (FAA); the FAA is proposing airworthiness directives, not buying products or services.
- **OEMs named**
  - **Pratt & Whitney Canada Corp. (P&WC):** PW814GA and PW815GA engines.
  - **The Boeing Company:** certain Model 787-8 airplanes.
- Products and scope
  - PW814GA and PW815GA engines: the proposed requirements cover 333 engines in total; the number for each model is not specified. Operators would incorporate revised life-limited-part limits, thresholds, and intervals into applicable airworthiness instructions and maintenance or inspection programs.
  - Certain Boeing 787-8 airplanes: the excerpt references inspections of wing fasteners, fuel tanks, surge tanks, and dry bays; an airworthiness limitation inspection; on-condition actions; concurrent requirements; and a maintenance-program revision. The specific airplane population and full requirements are not provided in the excerpt.
- Notable requirements and costs
  - The engine proposal follows Transport Canada AD CF-2025-71 and aims to prevent life-limited-part failure and resulting engine or aircraft damage.
  - FAA estimates labor costs of $85 per affected engine and no parts costs. This is an estimated compliance cost, not a contract value.

### Description

The FAA proposes a new airworthiness directive for all Pratt & Whitney Canada Corp. Model PW814GA and PW815GA engines. The proposal follows revisions to the airworthiness limitations section of the existing airworthiness limitations manual, introducing new or more restrictive limitations and intervals for life-limited parts. It would require updating the applicable manual or instructions for continued airworthiness and the existing approved maintenance or inspection program. Comments are due December 28, 2026.
