SUMMARY: This document corrects a technical bulletin date in 
airworthiness directive (AD) 98-07-03 that was incorrectly published in 
the Federal Register on March 24, 1998 (63 FR 14026). This AD is 
applicable to Bell Helicopter Textron, Inc. Model 412 helicopters and 
Agusta S.p.A Model AB 412 helicopters and requires a temporary 
reduction of the never-exceed velocity (Vne) limitation until an 
inspection of the tail rotor yoke (yoke) assembly for fatigue damage 
and installation of a redesigned yoke flapping stop are accomplished. 
Recurring periodic and special inspections to detect occurrences of 
yoke overload are also required.

DATES: Effective April 8, 1998.
    The incorporation by reference of certain publications listed in 
the regulations was previously approved by the Director of the Federal 
Register as of April 8, 1998 (63 FR 14026, March 24, 1998).
