You are responsible for having the actions 

required by this AD performed within the 

compliance times specified, unless the 

actions have already been done. 

(g) Inspection and Replacement 

Within 6,000 flight hours or 36 months 

after the effective date of this AD, whichever 

occurs first: Inspect the left and right AC 

generators to determine if the AC generator 

has a part number identified in step 3.B.(2) 

of the Accomplishment Instructions of 

Bombardier Service Bulletin 84–24–45, dated 

January 13, 2011, or has P/N 1152218–3. If 

an AC generator has a part number identified 

in Bombardier Service Bulletin 84–24–45, 

dated January 13, 2011, or has P/N 1152218– 

3, before further flight, replace the AC 

generator with a modified or new AC 

generator having P/N 1152218–6, in 

accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

84–24–45, dated January 13, 2011. 

(h) Parts Installation Prohibition 

After the effective date of this AD, no 

person may install an AC generator having 

P/N 1152218–5, 1152218–4, or 1152218–3 on 

any airplane.

SUMMARY: We are rescinding an 

airworthiness directive (AD) for all 

Piaggio Aero Industries S.p.A Model P– 

180 airplanes. That AD was prompted 

by mandatory continuing airworthiness 

information (MCAI) issued by the 

airworthiness authority for Italy. We 

issued that AD to prevent the brake 

hydraulic fluid from leaking because of 

the brake assembly rods contacting the 

brake valve tubing, which could result 

in the inability to adequately stop the 

airplane during ground operations. 

Since we issued that AD, we have 

determined this is no longer an unsafe 

condition and that regularly scheduled 

annual inspections address this subject. 

DATES: This AD is effective November 

21, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by rescinding AD 2000–07–11 

(65 FR 19305, April 11, 2000) that 

applies to the specified products. That 

NPRM was published in the Federal 

Register on July 19, 2012 (77 FR 42454). 

The MCAI states: 

After a 1999 training session during which 

conflicting inputs were given to the brake 

pads between pilot and copilot, a brake 

system rod was found deflected. The rod, in 

this bent condition, could possibly wear and 

damage the tubings connected to the brake 

valves, with consequent fluid leakage. 

Prompted by these findings, PAI issued 

Service Bulletin (SB) 80–0107, providing 

instructions for repetitive inspections of the 

affected rods and tubings. As this was 

considered to be a potentially unsafe 

condition, Registro Aeronautico Italiano 

(RAI), the predecessor of ENAC (Ente 

Nazionale per l’Aviazione Civile), issued 

Prescrizione di Aeronavigabilita` (PA) No. 

1999–219, which required the repetitive 

inspections as detailed in PAI SB 80–0107 

and, depending on findings, replacement of 

rod or tubing. 

Since that AD was issued, the repetitive 

inspections of SB 80–0107 have been 

included as regular tasks into the 

maintenance schedule of both Avanti and 

Avanti II aeroplanes. In addition, no other 

cases of brake system bent rods have been 

reported, nor have any rods been replaced for 

damage in the P.180 fleet since that 

occurrence. Based on the available 

information, this is no longer considered to 

be an unsafe condition. Prompted by this 

determination, PAI issued Revision ZZ of SB 

80–0107, which cancels the original SB 80– 

0107. 

For the reasons described above, this 

Notice is issued to cancel ENAC PA no. 

1999–219 dated 03 May 1999. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 42454, July 19, 2012) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that rescinding the AD will 

not affect air safety and will reduce the 

burden on the public. We will rescind 

the AD as proposed except for minor 

editorial changes. We have determined 

that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

42454, July 19, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 42454, 

July 19, 2012). 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

not have a substantial direct effect on 

the States, on the relationship between 

the national government and the States, 

or on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–200 

and –200C series airplanes. This AD 

was prompted by a report of elevator 

vibration and bearing swage failures. 

This AD requires, for certain airplanes, 

repetitive inspections for any 

discrepancies (such as a gap or a loose 

spacer) of the aft attach lugs for the 

elevator tab control mechanism, and 

replacement if necessary; and, for other 

airplanes, contacting the FAA for 

inspection or repair instructions and 

doing the work specified in those 

instructions. We are issuing this AD to 

detect and correct discrepancies in the 

aft attach lugs for the elevator tab 

control mechanism, which could result 

in elevator and tab vibration. 

Consequent structural failure of the 

elevator or horizontal stabilizer could 

result in loss of structural integrity and 

loss of airplane control. 

DATES: This AD is effective November 

21, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of November 21, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM published in the Federal 

Register on August 1, 2012 (77 FR 

45513). That NPRM proposed to require, 

for certain airplanes, repetitive 

inspections for any discrepancies (such 

as a gap or a loose spacer) of the aft 

attach lugs for the elevator tab control 

mechanism, and replacement if 

necessary; and, for other airplanes, 

contacting the FAA for inspection or 

repair instructions and doing the work 

specified in those instructions. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Boeing supports the NPRM (77 FR 

45513, August 1, 2012). 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

45513, August 1, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 45513, 

August 1, 2012). 

Costs of Compliance 

We estimate that this AD affects 200 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Inspection for Group 2 airplanes.7 work-hours × $85 per hour 

= $595 per inspection cycle.

$0 $595 per inspection cycle ...... $119,000 per inspection 

cycle. 

For Group 1 airplanes, we do not have 

definitive data that would enable us to 

provide cost estimates for the action 

specified in this AD. 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need these replacements:
