**Buyer:** Federal Aviation Administration, U.S. Department of Transportation
**Posted:** October 14, 2026
**Respond By:** December 01, 2026
**Identifier:** 2026-21008

The Federal Aviation Administration proposes a safety directive for selected Baykar Piaggio P-180 aircraft, not a purchase of products or services.
- **Government buyer:** Federal Aviation Administration (FAA), U.S. Department of Transportation.
- **OEM:** **Baykar Piaggio Aerospace S.p.A.** (also referred to as Piaggio or Piaggio Aerospace). EASA is referenced as the authority behind the underlying airworthiness information.
- **Affected aircraft:** 14 U.S.-registered Model P-180 airplanes, identified by manufacturer serial numbers 1032, 1036, 1037, 1039, 1040, 1043, 1063, 1065, 1074, 1079, 1089, 1106, 1108, and 1112.
- **Affected components:** Main-wing lower-skin external reinforcement doublers: left-hand, P/N 80-212457-001; right-hand, P/N 80-212457-002. These are identified as affected parts, not items being ordered.
- **Proposed work:** Repetitive high-frequency eddy-current (HFEC) inspections for corrosion, cracks, or other discrepancies around fasteners, with repair or other corrective action as required. Repairs for repairable corrosion must occur before the next flight; other discrepancies require an approved repair within its specified compliance time.
- **Referenced instructions:** Piaggio Aerospace Service Bulletin 80-0494 Rev. 1 for inspections and corrective actions; Service Bulletin 80-0482 Rev. 13 for applicability and weight-and-balance updates; and the Piaggio Aerospace Structural Repair Manual.
- **Opportunity status:** This is a proposed airworthiness directive, not a procurement solicitation; no purchase quantities, contract value, or procurement performance period are provided.

### Description

The FAA proposes a new airworthiness directive for certain Baykar Piaggio Aerospace S.p.A. Model P-180 airplanes. The proposal responds to reports of corrosion and cracks around the attaching fasteners on main wing lower-skin external reinforcement doublers. It would require repetitive high-frequency eddy current inspections and, depending on the findings, corrective action. Comments are due November 30, 2026.
