AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD requires 

repetitively inspecting the elevator 

control tabs for discrepancies and, if any 

discrepancies are found, taking 

necessary corrective actions to bring all 

discrepancies within acceptable 

tolerances. This AD also requires 

reporting certain inspection results to 

the FAA. This AD was prompted by an 

evaluation of revisions to the 

manufacturer’s maintenance manual 

that adds new repetitive inspections of 

the elevator control tabs. To require 

compliance with these inspections for 

U.S. owners and operators we are 

mandating the inspections through the 

rulemaking process. We are issuing this 

AD to add new repetitive inspections of 

the elevator control tabs. If these 

inspections are not done, excessive freeplay in the elevator control tabs could 

develop. This condition could lead to 

loss of tab control linkage and severe 

elevator flutter. Such elevator flutter 

could lead to possible loss of control. 

DATES: This AD is effective March 31, 

2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of March 31, 2011. 

ADDRESSES: For information about the 

revisions to the FAA-approved 

maintenance/inspection program 

identified in this AD, contact Viking Air

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to the 

specified products. That NPRM 

published in the Federal Register on 


jlentini on DSKJ8SOYB1PROD with RULES
Federal Register / Vol. 76, No. 37 / Thursday, February 24, 2011 / Rules and Regulations 10221 

December 7, 2010 (75 FR 75932). That 

NPRM proposed to require repetitively 

inspecting the elevator control tabs for 

discrepancies and, if any discrepancies 

are found, taking necessary corrective 

actions to bring all discrepancies within 

acceptable tolerances. 

That NPRM also proposed a reporting 

requirement requesting information 

when the total maximum free play of 

the elevator servo tab and trim tab 

relative to the elevator exceeds 1.0 

degree (this is equal to a maximum 

displacement of 0.070′′ at the trailing 

edge of the servo tab). Collecting this 

information will help us better 

understand the service history related to 

excessive free-play in the elevator 

control tabs for various Model DHC–3 

engine configurations. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data 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 for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Interim Action 

We are continuing to evaluate the 

cause of the unsafe condition identified 

in this AD to enable us to obtain better 

insight into the nature, cause, and 

extent of excessive free-play in the 

elevator control tabs. Based on this 

evaluation, we may consider further 

rulemaking. 

Costs of Compliance 

We estimate that this AD affects 65 

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 .............. 1 work-hour × $85 per hour 

= $85 per inspection cycle.

Not applicable ...................... $85 per inspection cycle ...... $5,525 per inspection cycle. 

We estimate the following costs to do 

any necessary follow-on actions that 

will be required based on the results of 

the inspection. We have no way of 

determining the number of airplanes 

that may need this repair/replacement: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Minimum repair ................................ 1 work-hour × $85 per hour = $85 ............................................................ $50 $135 

Moderate repair ............................... 3 work-hours × $85 per hour = $255 ........................................................ 150 405 

Maximum repair ............................... 6 work-hours × $85 per hour = $510 ........................................................ 450 960 

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 

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 

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.

Unsafe Condition 

(e) This AD results from an evaluation of 

revisions to the manufacturer’s maintenance 

manual that adds new repetitive inspections 

to the elevator control tabs. To require 

compliance with these inspections for U.S. 

owners and operators we are mandating these 

inspections through the rulemaking process. 

We are issuing this AD to add new repetitive 

inspections of the elevator control tabs. If 

these inspections are not done, excessive 

free-play in the elevator control tabs could 

develop. This condition could lead to loss of 

tab control linkage and severe elevator 

flutter. Such elevator flutter could lead to 

possible loss of control. 

Compliance 

(f) Comply with this AD within the 

compliance times specified, unless already 

done. 

Actions Compliance Procedures 

(1) Inspect the elevator control tabs for discrepancies. Initially within the next 50 hours time-in-service (TIS) after March 31, 2011 (the effective

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Compass mismatch (up to loss of heading 

information) were reported by operators, due 

to ferro-magnetic masses (like the telescopic 

Tow-Bar) stowed in the baggage 

compartment. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

March 31, 2011. 

On March 31, 2011, the Director of the

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 was published in the Federal 

Register on November 3, 2010 (75 FR 

67639). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Compass mismatch (up to loss of heading 

information) were reported by operators, due 

to ferro-magnetic masses (like the telescopic 

Tow-Bar) stowed in the baggage 

compartment. A limitation was added to the 

approved Airplane Flight Manual, stating 

that the towing bar P/N 01–1227–0000 or 

similar ferromagnetic masses are prohibited 

to be carried in the baggage compartment. 

We require the incorporation of Piaggio 

Aero Industries S.p.A. and Piaggio Aero 

Industries (Piaggio) Temporary Change 

No. 7, into the Pilot’s Operating 

Handbook and EASA Approved 

Airplane Flight Manual Rep. 6591, 

issued: February 24, 2009, and 

Temporary Change No. 11 into the 

EASA Approved Airplane Flight 

Manual Rep. 180–MAN–0010–01100, 

issued: February 24, 2009, and 

installation of a placard. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Comment Issue: Study Relocation of 

Magnetic Flux Valves 

James Wright stated that investigation 

into the feasibility of relocating the 

magnetic flux valves to an area less 

susceptible to magnetic interference 

may be a better course of action. We 

infer that the commenter requests that 

we withdraw the AD action and relocate 

the magnetic flux valves to an area less 

susceptible to magnetic interference. 

We do not agree with the commenter. 

The current airplane flight manual 

limitation stipulates: 

The towing bar TRONAIR p/n 01–1227– 

0000 or other ferromagnetic masses with 

comparable mass and length are prohibited to 

be carried in the baggage compartment. 

Additionally, Piaggio evaluated the 

possibility of relocating the flux valve 

and concluded it should remain in its 

current location. Piaggio confirmed that 

a new tow bar made of aluminum is 

available and can be used on Model 

PIAGGIO P–180 airplanes.
