AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain serial numbers (S/Ns) of Ontic 

Engineering and Manufacturing, Inc. 

propeller governors, part numbers (P/ 

Ns) C210776, T210761, D210760, and 

J210761. This proposed AD would 

require removal of the affected propeller 

governors from service. This proposed 

AD results from three reports received 

of failed propeller governors. We are 

proposing this AD to prevent loss of 

propeller pitch control, damage to the 

propeller governor, and internal damage 

to the engine, which could prevent 

continued safe flight or safe landing. 

DATES: We must receive any comments 

on this proposed AD by May 14, 2010.

Discussion 

We received three reports of failure of 

Ontic Engineering and Manufacturing, 

Inc. propeller governors. One of the 

reports was of a Diamond DA–40 

airplane losing propeller pitch control 

during flight. The propeller governor 

controls propeller pitch by regulating oil 

pressure to the propeller pitch change 

mechanism. Changes in governor oil 

pressure are made by small changes in 

axial displacement of the governor’s 

pilot valve plunger assembly. A fly 

weight governor opposes a compressed 

spring that rides on a collar which forms 

a part of the pilot valve plunger 

assembly. Investigation revealed that the 

set screw securing the collar to the pilot 

valve plunger assembly shaft may not be 

installed properly on a batch of parts 

permitting the pilot valve plunger to 

float on the shaft. The pilot valve shaft 

plunger and captive thrust bearing are 

then free to move axially along the pilot 

valve shaft. When the pilot valve is 

unconstrained in the axial direction, the 

propeller governor cannot control oil 

pressure to the propeller pitch control 

mechanism. This results in a loss of 

propeller pitch control. Further, 

concurrent thrust bearing failure 

permits bearing debris to flow with the 

oil into the engine lubrication system. 

The engine in the incident airplane was 

internally damaged as a result of a 


emcdonald on DSK2BSOYB1PROD with PROPOSALS
Federal Register / Vol. 75, No. 49 / Monday, March 15, 2010 / Proposed Rules 12149 

propeller governor bearing ball 

becoming lodged between the valve 

lifter and engine case. This condition, if 

not corrected, could result in loss of 

propeller pitch control, damage to the 

propeller governor, and internal damage 

to the engine, which could prevent 

continued safe flight or safe landing. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of Ontic Engineering 

and Manufacturing, Inc. Mandatory 

Service Bulletin (MSB) No. SB–DES– 

353, Revision A, dated December 16, 

2009. That MSB lists the affected 

propeller governors by P/N and S/N, 

and describes procedures for returning 

them to the manufacturer for repair. 

FAA’s Determination and Requirements 

of the Proposed AD 

We have evaluated all pertinent 

information and identified an unsafe 

condition that is likely to exist or 

develop on other products of this same 

type design. We are proposing this AD, 

which would require removal of 

affected propeller governors from 

service. The proposed AD would require 

you to use the service information 

described previously to identify the 

affected S/Ns of propeller governors. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 45 propeller governors 

installed on airplanes of U.S. registry. 

We also estimate that it would take 

about four work-hours per airplane to 

perform the proposed actions, and that 

the average labor rate is $85 per workhour. Required repair parts would cost 

about $842 per propeller governor. 

Based on these figures, we estimate the 

total cost of the proposed AD to U.S. 

operators to be $83,790. Our cost 

estimate is exclusive of possible 

warranty coverage. 

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 have determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would 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 the proposed 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); and 

3. Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD. You may get a copy 

of this summary at the address listed 

under ADDRESSES.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated 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: 

This Airworthiness Directive (AD) is 

prompted due to the discovery of corrosion 

at the bonding strap connections on the left 

and right lower longerons between fuselage 

frames 1 and 1A. The possibility of corrosion 

is increased because of the high electrical 

current flow between the tinned copper 

terminal lug of the bonding strap and the 

aluminum longeron. 

Such a condition, if left uncorrected, could 

lead to failure of the longeron and will 

prejudice the structural integrity of the 

aircraft. 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by April 29, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The Federal Office of Civil Aviation 

(FOCA), which is the aviation authority 

for Switzerland, has issued FOCA AD 

HB–2010–001, dated February 12, 2010 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

This Airworthiness Directive (AD) is 

prompted due to the discovery of corrosion 

at the bonding strap connections on the left 

and right lower longerons between fuselage 

frames 1 and 1A. The possibility of corrosion 

is increased because of the high electrical 

current flow between the tinned copper 

terminal lug of the bonding strap and the 

aluminum longeron. 

Such a condition, if left uncorrected, could 

lead to failure of the longeron and will 

prejudice the structural integrity of the 

aircraft. In order to correct and control the 

situation, this AD requires a one time 

inspection of the longeron structure and the 

terminal lugs of the bonding straps for signs 

of corrosion. 

For left and right lower longerons where 

corrosion is found during the 

inspection, the MCAI also requires 

repair of any longeron where corrosion 

is found. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

PILATUS Aircraft Ltd. has issued 

PILATUS PC–7 Service Bulletin No. 53– 

007, dated January 5, 2010. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of the Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences between this Proposed AD 

and the MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 10 products of U.S. registry. 

We also estimate that it would take 

about 4.5 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $3,825, or $383 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take
