Airworthiness Directives; PILATUS

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; rescission; request 

for comments 

SUMMARY: We are rescinding an 

airworthiness directive (AD) for all 

PILATUS AIRCRAFT LTD. Models PC– 

12, PC–12/45, and PC–12/47 airplanes. 

This AD results from mandatory 

continuing airworthiness information 

(MCAI) issued by the aviation authority 

of another country to identify and 

correct an unsafe condition on an 

aviation product. We issued that AD to 

mandate new life limits for the pitch 

trim actuator and pitch trim actuator 

attachment parts. If these new 

limitations were not mandated, the 

pitch trim actuator and the pitch trim 

actuator components could fail. This 

failure could lead to an unsafe flying 

configuration. Since we issued that AD, 

we have determined that the unsafe 

condition addressed in that AD is now 

addressed in another AD. 

DATES: This AD is effective March 25, 

2013. 

We must receive comments on this 

AD by May 9, 2013. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to

SUPPLEMENTARY INFORMATION: 

Discussion 

On March 27, 2008, we issued AD 

2008–07–11, Amendment 39–15452 (73 

FR 18433, April 4, 2008). That AD 

required actions intended to address an 

unsafe condition on the products listed 

above. 

AD 2008–07–11, Amendment 39– 

15452 (73 FR 18433, April 4, 2008) was 

based on results of a full-scale fatigue 

test of the pitch trim actuator on 

PILATUS AIRCRAFT LTD. Models PC– 

12, PC–12/45, and PC–12/47 airplanes. 

The life-limit was extended and the 

time between overhaul (TBO) was 

reduced. In addition, based on the 

results of the fatigue test, a life-limit of 

the pitch trim actuator attachment had 

been established. 

These new limitations were 

incorporated into the airworthiness 

limitations section of the Pilatus PC–12 

Airplane Maintenance Manual (AMM) 

12–A/AMP–04, chapter 4, revision 10, 

dated October 26, 2007. 

The new limitations for the pitch trim 

actuator TBO were moved from Chapter 

5: Time Limits/Maintenance Checks, to 

Chapter 4: Structural, Component and 

Miscellaneous—Airworthiness 

Limitations. Since both chapter 4 and 

chapter 5 are mandatory within the 

European and Swiss airworthiness 

systems, it was not necessary for the 

European Aviation Safety Agency 

(EASA) and the Federal Office of Civil 

Aviation (FOCA) to issue an AD to 

mandate these new limitations. 

The only way the FAA can mandate 

the implementation of changes to the 

airworthiness limitations section of an 

FAA-approved maintenance program is 

by AD action. 

On February 8, 2013, we issued AD 

2012–26–16, Amendment 39–17311 (78 

FR 11572, February 19, 2013). AD 2012– 

26–16 also requires incorporating new 

revisions into the Limitations section, 

Chapter 4, of the Pilatus PC–12 AMM. 

The limitations were revised to include 

an inspection of the wing main spar 

fastener holes at rib 6 for cracks. 

After issuing AD 2012–26–16, 

Amendment 39–17311 (78 FR 11572, 

February 19, 2013), we determined that 

AD 2008–07–11 should have been 

superseded by AD 2012–26–16. Since 

AD 2008–07–11 requires incorporating 

an earlier version of the airworthiness 

limitations section of the AMM, it could 

cause confusion for the owners/ 

operators and could result in missed 

inspections and replacements required 

by AD 2012–26–16. Therefore, the need 

to continue to address this subject as an 

unsafe condition through AD 2008–07– 

11 is no longer necessary. 

FAA’s Determination 

We are issuing this AD because we 

evaluated all available information and 

determined the existing AD is no longer 

necessary. 

AD Requirements 

This AD would rescind AD 2008–07– 

11, Amendment 39–15452 (73 FR 

18433, April 4, 2008). 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists or could 

develop that requires the immediate 

adoption of this AD. The FAA has found 

that the risk to the flying public justifies 

waiving notice and comment prior to 

adoption of this rule because the unsafe 

condition addressed in AD 2008–07–11, 

Amendment 39–15452 (73 FR 18433, 

April 4, 2008) is currently addressed in 

AD 2012–26–16, Amendment 39–17311

17866 Federal Register / Vol. 78, No. 57 / Monday, March 25, 2013 / Rules and Regulations 

(78 FR 11572, February 19, 2013). 

Allowing the airworthiness limitation 

section (ALS) required by AD 2008–07– 

11 to remain valid could cause 

confusion as to what is required and 

this could introduce an unsafe 

condition if certain areas were not 

inspected. Therefore, we determined 

that notice and opportunity for public 

comment before issuing this AD are 

impracticable and that good cause exists 

for making this amendment effective in 

fewer than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2008–0070; 

Directorate Identifier 2007–CE–098– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

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 that 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.
