(URGENT)
In plain language (FlightFinder summary)
The FAA is asked to immediately implement the ultrasonic inspection program for Hamilton Standard propeller blades specified in paragraph (a)(2) of Airworthiness Directive 95-05-03, regardless of whether the requirements of paragraph (d) of that AD have already been met. Additionally, the FAA must require that any propeller blades with 1,250 cycles since their last ultrasonic inspection or since the visual and borescope inspection required by paragraph (d) undergo the initial inspection before further flight.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
