The FAA has proposed issuing an airworthiness directive ordering operators to replace the proximity sensors in the 787-8.
The AD’s creation was prompted by “numerous reports of failures of the proximity sensors”, the FAA confirmed.
Such failures, it warned, could cause runway excursions in the case of adverse weather conditions or short runways.
The AD requires the replacement of slat skew detection mechanism assemblies within two years and will affect 15 aircraft operating in the US.
The FAA estimates that the fix will cost operators $14,000. Operators have until January12 to comment on the proposed AD.
