Airworthiness Directives; de Havilland Model DHC-8-102, -103, and 
-106, Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

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

SUMMARY: This document corrects a typographical error that appeared in 
airworthiness directive (AD) 95-12-12 that was published in the Federal 
Register on June 13, 1995 (60 FR 31063). The typographical error 
resulted in a reference to a part number that does not exist. This AD 
is applicable to certain de Havilland Models DHC-8-102, -103, and -106 
series airplanes and requires repetitive operational testing of the 
stall warning computers.

DATES: Effective June 28, 1995.
    The incorporation by reference of certain publications listed in 
the regulations was previously approved by the Director of the Federal 
Register as of June 28, 1995 (60 FR 31063, June 13, 1995).

FOR FURTHER INFORMATION CONTACT: Peter Cuneo, Aerospace Engineer, 
Systems and Equipment Branch, ANE-172, FAA, New York Aircraft 
Certification Office, Engine and Propeller Directorate, 10 Fifth 
Street, Third Floor, Valley Stream, New York 11581, telephone (516) 
256-7506; fax (516) 568-2716.

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 95-12-12, 
amendment 39-9262, applicable to certain de Havilland Model DHC-8-102, 
-103, and -106 series airplanes, was published in the Federal Register 
on June 13, 1995 (60 FR 31063). That AD requires repetitive operational 
testing of the stall warning computers and replacement of non-
operational stall warning computers with new or serviceable units. That 
AD also provides an optional terminating action for the repetitive 
operational tests.
    As published, that AD contained a typographical error in paragraph 
(b), which describes the optional terminating action. That paragraph 
stated that replacement of stall warning computers having part number 
(P/N) ``3605-5, -6, or -7'' with new stall warning computers having P/N 
3605-8 would constitute terminating action. However, ``P/N 3605-7'' was 
inadvertently indicated in that paragraph instead of the correct part 
number of ``P/N 3605-4.'' (In fact, P/N 3605-7 does not exist.) In all 
other parts of the published AD and its preamble, these part numbers 
were correctly cited as ``P/N 3605-4, -5, and -6.''
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.

    The effective date of the AD remains June 28, 1995.
