Overview

MANDATORY RECURRING INSPECTION OF TAIL BOOM VERTICAL FIN SPAR ASSEMBLY FOR ALL UH--1 SERIES AIRCRAFT, TB 1-1520-210-30-01

SOF UH--1--99--03 required inspection of the vertical fin spar for cracks and debonding.
Detailed inspection procedures were provided in the previos version of TB 1--1520--210--30--01 dated 9 June 1999 that were not included in the message version of SOF UH--1--99--03.

The SOF stated that if the vertical fin spar is found cracked, the boom assembly shall not be used. The UH--1maintenancemanual, TM55--1520--210--23--1, allows for repair of vertical fin spar cracks near the 90 degree gearbox mount attachment area. It has been determined that this repair is acceptable and may continue to be used providing that a recurring visual inspection be performed on the spar for crack growth.
