The National Transportation Safety Board on Thursday issued a formal and urgent safety recommendation to the Federal Aviation Administration and its Canadian counterpart that they mandate an immediate one-time inspection of a critical component on all DHC-3 Otter seaplanes.
In an investigation update, the NTSB cited "an immediate safety hazard because it could result in a reduction or loss of pitch control during flight."
In an interview, NTSB Chair Jennifer Homendy stressed that the safety agency wants operators of the aircraft "to conduct these inspections immediately before the planes fly again."
