Federal Register / Vol. 73, No. 208 / Monday, October 27, 2008 / Rules and Regulations
Effective Date
AD if requested using the procedures found
in 14 CFR 39.19.
(a) This airworthiness directive (AD)
becomes effective December 1, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to GE CT58 series
turboshaft engines with a compressor spool,
part number (P/N) 5920T82G07,
6010T57G07, or 6010T57G08, installed.
These engines are installed on, but not
limited to, Sikorsky S–61A, S–61L, S–61N,
S–61R, S–62, and Columbia 107–II
helicopters.
Unsafe Condition
(d) This AD results from reports of cracks
originating from the inner faces of the locking
screw holes in the compressor spool. We are
issuing this AD to prevent cracks due to
repetitive heavy lift (RHL) missions. Cracks
could result in an uncontained rotor burst
and damage to, or loss of, the helicopter and
serious injuries to any person onboard.

(l) GE Alert Service Bulletin CT58 S/B 72–

Compliance
(e) You are responsible for having the
actions required by this AD performed within
the compliance times specified unless the
actions have already been done.
Recalculating Compressor Spool Cycles
(f) Within 30 days after the effective date
of this AD, recalculate the life of compressor
spools, P/N 5920T82G07, 6010T57G07, or
6010T57G08, using an RHL mission
multiplying factor of both 3.7 cycles per hour
and 6.0 cycles per hour. GE Alert Service
Bulletin CT58 S/B 72–A0162, Revision 12,
dated April 17, 2008, contains information
on calculating life cycles for the compressor
spools.

Removing Compressor Spools Based on the
New Recalculated Cycles
(g) Before January 1, 2010, remove the
compressor spools, P/N 5920T82G07,
6010T57G07, or 6010T57G08, at the earlier of
when:
(1) The compressor spool reaches its part
life limit as calculated using an RHL
multiplying factor of 3.7, or
(2) You can see the spool at shop visit after
it has reached its part life limit using an RHL
multiplying factor of 6.0.
(h) On January 1, 2010 and thereafter,
remove the engine before the compressor
spool exceeds its part life limit as calculated
using an RHL multiplying factor of 6.0.
(i) As of January 1, 2010, don’t use an RHL
multiplying factor of 3.7 to calculate the life
of the compressor spool.
Installation Prohibition
(j) After the effective date of this AD, don’t
install any engine that has a compressor
spool installed that meets or exceeds the life
limits as calculated in paragraph (g)(1)
through (g)(2) or (h) of this AD.
Alternative Methods of Compliance
(k) The Manager, Engine Certification
Office, has the authority to approve
alternative methods of compliance for this

[Docket No. FAA–2000–7953; Amendment
No. 417]
RIN 2120–AG37
Licensing and Safety Requirements for
Launch
Federal Aviation
Administration, DOT.
ACTION: Final rule; technical
amendment.
AGENCY:
SUMMARY: This action corrects reference
errors that appeared in a final rule the
FAA published in the Federal Register
on August 25, 2006. The final rule
amended commercial space
transportation regulations governing the
launch of expendable launch vehicles.
In that final rule, the FAA inadvertently
referenced incorrect sections. The intent
of this action is to correct this minor
error in the regulation to ensure the
requirement is clear and accurate.
DATES: Effective October 27, 2008.

SUPPLEMENTARY INFORMATION: On August
25, 2006, the FAA published a final rule
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
in the Federal Register (71 FR 50537)
that, among other changes, amended
§ 417.25(c)(3). The FAA inadvertently
referenced incorrect sections in 14 CFR
417.25(c)(3). As published, this
provision requires a post launch report
to identify any flight environment not
consistent with the maximum predicted
environment as required by § 417.307(b)
and any measured wind profiles not
consistent with the predictions used for
the launch, as required by
§ 417.217(d)(2). These references are
incorrect. They should refer launch
operators to Appendix D 417.7(b) and
Appendix A 417.7(g)(3), respectively.
This amendment will not impose any
additional restrictions on operators
affected by these regulations.
Technical Amendment
This technical amendment corrects
the references in § 417.25(c)(3).
Justification for Immediate Adoption
Because this action merely corrects a
reference made in the published rule,
the FAA finds that notice and public
comment under 5 U.S.C. 553(b) is not
necessary. For the same reason, the FAA
finds good cause exists under 5 U.S.C.
553(d) for making this rule effective
upon publication.

recordkeeping requirements, Rockets,

■ Accordingly, Title 14 of the Code of
Federal Regulations (CFR) part 417 is
amended as follows:
PART 417—LAUNCH SAFETY
1. The authority citation for part 417
continues to read as follows:
■
Authority: 49 U.S.C. 70101–70121.
2. Amend § 417.25 by revising
paragraph (c)(3) to read as follows:
■
§ 417.25
Post launch report.
(c) * * *
(3) For the launch of launch vehicle
flown with a flight safety system,
identify any flight environment not
consistent with the maximum predicted
environment as required by D 417.7(b)
and any measured wind profiles not
consistent with the predictions used for
the launch, as required by § 417.7(g)(3);
