Torn Seals Could Jam Airplane Landing Gear, FAA Panics

## Summary

If you fly or work with Airbus Defense and Space CN-235 planes, listen up! The FAA found a problem where torn seals can jam emergency gear cables, which is a big safety no-no. Starting February 12, 2025, owners must regularly check and replace these parts to keep flights safe—so plan for some inspections and fixes that might cost time and money.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-200, and CN-235-300 airplanes. This AD was prompted by a torn bulkhead seal found jamming the nose landing gear (NLG) emergency cable pulley. Due to the similarity of design, the main landing gear (MLG) emergency cable pulley could be exposed to the same failure mode. This AD requires repetitive inspections and corrective actions for damage of affected bulkhead seals and retainer rings, and repetitive replacement of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- Mandatory Inspections and Part Replacements: cost, high. If you own or operate an Airbus Defense and Space CN-235 (models CN-235, CN-235-200, CN-235-300), you must follow repetitive inspections and corrective actions for damaged bulkhead seals and retainer rings, and repetitive replacement of affected parts as specified in EASA AD 2024-0054. These requir…
- Small U.S. Fleet Affected; Per-Repair Cost Estimate: benefit, low. The FAA estimates this AD affects 10 CN-235 airplanes on the U.S. registry. The FAA estimates an on-condition action (if needed after inspection) costs about $535 per airplane (2 work-hours x $85 = $170 labor plus $365 parts).
