Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2009–14–12 Pratt & Whitney Canada Corp: 

Amendment 39–15962. Docket No. 

FAA–2009–0046; Directorate Identifier 

2008–NE–05–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective August 13, 2009. 

Affected ADs 

(b) None. 

(c) This AD applies to Pratt & Whitney 

Canada Corp. (P&WC) Models PW305A and 

PW305B turbofan engines with high pressure 

compressor (HPC) drum rotor assemblies, 

post P&WC Service Bulletin (SB) PW300–72– 

24287 but without P&WC SB PW300–72– 

24376, installed. These engines are installed 

on, but not limited to, Bombardier Learjet 

M60 and Hawker Beechcraft 1000 series 

airplanes. 

Reason 

(d) P&WC has determined that the PostService Bulletin (SB) PW300–72–24287 High 

Pressure Compressor (HPC) drum rotor 

assemblies P/N 30B2478 and 30B2542 on 

PW305A and 305B engines with single stage 

coated labyrinth seals, are susceptible to 

developing significant cracks in the region of 

the labyrinth seal. 

We are issuing this AD to detect cracks in the 

HPC drum rotor assembly, which could lead 

to an uncontained failure of the drum rotor 

assembly and damage to the airplane. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

(1) Within 500 flight hours after effective 

date of this directive, borescope-inspect the 

interiors of affected HPC rotor assemblies for 

cracks. If a crack is found, remove the engine 

before next flight for HPC drum rotor 

replacement. Pratt & Whitney Maintenance 

Manual, Chapter 72–00–00, contains 

guidance on borescope inspection. 

Credit for Previous Inspections 

(2) Inspection of affected HPC drum rotor 

assembly per P&WC SB PW300–72–24462 

and or SB PW305 MM 05–20–00 inspection 

requirements prior to the effective date of 

this directive satisfies the requirements of 

paragraph (e)(1) of this AD. 

(3) Repeat borescope inspection per 

paragraph (e)(1) of this AD, at intervals not 

exceeding 1,350 flight cycles. If a crack is 

found, remove the engine before next flight 

for HPC rotor drum replacement. 

Optional Terminating Action 

(4) Replacement of the affected HPC rotor 

assembly P/N 30B2478 or 30B2542 with PostSB PW300–72–24376 assembly P/N 

31B6325–01 or later superseding P/N, will 

constitute terminating action for the 

inspection requirements of the above 

paragraphs (e)(1) and (e)(2) of the corrective 

action requirements of this AD. 

Other FAA AD Provisions 

(f) Alternative Methods of Compliance 

(AMOCs): The Manager, Engine Certification 

Office, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19.

SUMMARY: The Federal Aviation 

Administration (FAA) is making minor 

technical changes to a final rule 

published in the Federal Register on 

May 14, 2009. That final rule amended 

the FAA’s drug and alcohol regulations 

to place them in a new part. In that final

SUPPLEMENTARY INFORMATION: The 

Federal Aviation Administration (FAA) 

published a document in the Federal 

Register May 14, 2009, in 74 FR 22649 

that amended the regulations governing 

FAA-required drug and alcohol testing 

requirements. The FAA inadvertently 

did not include an instruction to revise 

language in § 91.146 to change the 

reference to the drug and alcohol testing 

program regulation title from the old (14 

CFR part 121, appendices I and J) to 

new, 14 CFR part 120. This amendment 

will not impose any additional 

restrictions on operators affected by 

these regulations. 

Technical Amendment 

The technical amendment will further 

amend part 91 by updating a crossreference in § 91.146(b).

Revisions to Digital Flight Data 

Recorder Regulations for Boeing 737 

Airplanes and for All Part 125 

Airplanes 

AGENCY: Federal Aviation 

Administration, DOT. 

ACTION: Final rule; correction. 

SUMMARY: The Federal Aviation 

Administration (FAA) is amending a 

final rule published in the Federal 

Register on December 2, 2008. That 

final rule amended the regulations 

governing flight data recorders to 

increase the number of digital flight data 

recorder parameters for all Boeing 737 

series airplanes manufactured after 

August 18, 2000. The rule also adopts a 

prohibition on deviations from flight 

recorder requirements for all airplanes 

operated under part 125. In our changes 

to part 125, the FAA incorrectly 

referenced the appendix containing 

airplane flight recorder specifications as 

appendix M when it is actually 

appendix E. 

DATES: Effective Date: These 

amendments become effective July 9, 

2009.

SUPPLEMENTARY INFORMATION: The 

Federal Aviation Administration 

published a final rule entitled 

‘‘Revisions to Digital Flight Data 

Recorder Regulations for Boeing 737 

Airplanes and for All Part 125 

Airplanes’’ in the Federal Register on 

December 2, 2008 (73 FR 73171). That 

final rule amended the regulations 

governing flight data recorders to 

increase the number of digital flight data 

recorder parameters for all Boeing 737 

series airplanes manufactured after 

August 18, 2000. The rule also adopted 

a prohibition on deviations from flight 

recorder requirements for all airplanes 

operated under part 125. 

Following publication of the final 

rule, an individual contacted us noting 

that the amended language in 

§ 125.226(f)(1) references ‘‘appendix M 

to this part’’ when the correct appendix 

is appendix E. Upon reviewing our 

other changes to part 125, we noted the 

same incorrect reference in the amended 

language of § 125.226(n). 

This document makes the appropriate 

amendatory changes to §§ 125.226(f)(1) 

and 125.226(n) to correctly reference 

appendix E to part 125. 

Correcting Amendment 

This correcting amendment will 

clarify the references to appendix E to 

part 125 in §§ 125.226(f)(1) and 

125.226(n).
