Airworthiness Directives; Jetstream Model 4101 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: This document corrects information in an existing 
airworthiness directive (AD), applicable to certain Jetstream Model 
4101 airplanes, that requires a one-time inspection for damage caused 
by arcing and overheating of the electrical ground posts (``earth 
posts'') and ground cables for the direct current (DC) power generation 
and propeller de-icing systems of the left and right engines; and 
repair and replacement, if necessary. This action corrects the AD 
number assigned to that AD.

DATES: Effective March 14, 1997.
    The incorporation by reference of certain publications listed in 
the regulations was previously approved by the Director of the Federal 
Register as of March 14, 1997 (62 FR 5743, February 7, 1997).

FOR FURTHER INFORMATION CONTACT: William Schroeder, Aerospace Engineer, 
Standardization Branch, ANM-113, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (206) 
227-2148; fax (206) 227-1149.

SUPPLEMENTARY INFORMATION: On January 29, 1997, the FAA issued AD 97-
03-12, amendment 39-9917 (62 FR 5743, February 7, 1997), which is 
applicable to certain Jetstream Model 4101 airplanes. That AD requires 
a one-time inspection for damage caused by arcing and overheating of 
the electrical ground posts (``earth posts'') and ground cables for the 
direct current (DC) power generation and propeller de-icing systems of 
the left and right engines; and repair and replacement, if necessary. 
That action was prompted by reports indicating that earth posts on some 
airplanes had failed due to overheating. The actions specified by that 
AD are intended to prevent potential consequences of overheating, such 
as failure of the DC power generation and propeller de-icing systems.
    Since the issuance of that AD, the FAA has become aware of the fact 
that the document that was published in the Federal Register contained 
the incorrect AD number that had been assigned to that action. The 
published version indicated an AD number of 96-03-12. However, the 
correct AD number is 97-03-12.
    Action is taken herein to correct the AD number to 97-03-12 and to 
correctly add the AD as an amendment to section 39.13 of the Federal 
Aviation Regulations (14 CFR 39.13).
    The effective date of the rule remains March 14, 1997.
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.
