The FAA says a Tecnam P2006T’s left aileron can partly tear loose when a hinge pin goes missing

The Federal Aviation Administration has ordered operators of Tecnam P2006T twin-engine airplanes to inspect the hinges and cotter pins on both ailerons within 25 flight hours or 30 days, whichever comes first. The order, airworthiness directive 2026-19-06, took effect on October 13, 2026. It was triggered by a single reported case in which the left aileron of a P2006T partly came away from the wing because a hinge pin was missing.

An aileron is the hinged panel on the trailing edge of each wing that the pilot moves with the control wheel or stick to roll the airplane. Two hinged surfaces, one per wing, work in opposition, so losing hold of one removes the pilot’s ability to roll the airplane the way the controls command. Each aileron hangs on several hinges, and a small pin through each hinge is held in place by a cotter pin, which is a split metal pin bent over so the hinge pin cannot slide out.

A missing hinge pin and the FAA’s unsafe condition

The directive was published in the Federal Register on September 28, 2026, as document 2026-19760, and carries amendment number 39-23473. In the FAA’s own words, the AD “was prompted by a report of partial detachment of the left aileron due to a missing hinge pin.” The agency adds that the unsafe condition, “if not addressed, could lead to detachment of an aileron, possibly resulting in loss of control of the airplane.” The notice covers the Model P2006T built by Costruzioni Aeronautiche Tecnam S.p.A. and does not extend to other Tecnam models.

The rule is the U.S. version of a European order. The European Union Aviation Safety Agency issued EASA AD 2026-0124 on July 1, 2026, and the FAA’s text relies on it. EASA’s investigation found the outboard hinge pin of the affected aileron was missing, and that a missing or broken cotter pin could let a hinge pin migrate far enough for the outboard hinge halves to separate. Inspections of two other airplanes then turned up broken and incorrectly installed cotter pins, and cracks in some aileron hinges. EASA called its order an interim action and said further action may follow.

The inspection and the 25-hour clock

The compliance time runs from the October 13, 2026 effective date. Operators have 25 flight hours or 30 days, whichever occurs first, which puts the calendar limit at November 12, 2026 for an airplane that flies little. The work is a one-time detailed visual inspection of the inboard and outboard hinges on both ailerons, plus the cotter pins, following Tecnam Service Bulletin 995-CS-Ed. 1, Revision 2, dated September 18, 2026. Inspections already done under the earlier April 21, 2026 original or the August 25, 2026 first revision are credited. Although the reported case involved the left aileron, the check applies to the right one as well.

Findings change what happens next. A discrepant cotter pin must be replaced and secured before the airplane flies again. If a hinge is cracked or damaged, the operator has to contact the FAA, EASA or Tecnam’s EASA-approved design organization for repair instructions before further flight. The FAA’s summary also says the inspection looks for warping of the hinges or hinge pin, scratched paint and a missing or broken torque stripe. Because the rule sits in 14 CFR part 39, flying an airplane that has not met it is a violation, not a recommendation.

The FAA’s stated reason for acting is short: the unsafe condition “is likely to exist or develop on other products of the same type design,” as the official PDF puts it.

Cost estimate and the 102 U.S. airplanes

The FAA estimates the directive affects 102 U.S.-registered airplanes. It counts one work-hour of labor at $85 per airplane for the inspection, a total of $8,670 for U.S. operators. If a cotter pin has to be replaced, the agency puts the parts-and-labor figure at $86 per affected pin, and it says it cannot yet estimate hinge repairs because those depend on what an inspection finds. The comment record sits in docket FAA-2026-11784, where the supporting documents are posted for anyone who wants the service bulletin and cost basis.

Inside the FAA, questions go to Anthony Kenward, an aviation safety engineer in the agency’s Westbury, New York, office. The notice gives no accident total, no injury count and no estimate of how often a hinge pin goes missing across the fleet. That gap matters for reading the directive correctly. The FAA is acting on one reported occurrence plus the cracked and badly pinned hardware EASA found on two further airplanes, and it says the same condition is likely to exist or develop on other products of the same type design.

For owners the practical reading is narrow and checkable. The defect is a small, cheap piece of hardware that is supposed to keep a hinge pin from walking out, and the fix for most airplanes is a look, followed by a new pin if one is broken or absent. The harder case is a cracked hinge, which grounds the airplane until an approved repair exists. Because EASA labeled its action interim, a second directive could follow once Tecnam and the regulators have more inspection results to read.
