A United Airlines Boeing 777-200 lost an engine cowling on approach to Honolulu International airport on 13 February.
The aircraft operating flight 1175 to Honolulu from San Francisco landed safely with all passengers deplaning at the gate, the Chicago-based carrier says.
United adds that the pilots followed all "necessary protocols" before landing in Honolulu.
The 777-200 (registration N773UA, MSN 26929) has two Pratt & Whitney PW4077 engines, Flight Fleets Analyzer shows. It was delivered new to United in January 1996.
The aircraft had 89,142 hours and 16,221 cycles in November 2017, the database shows.
