new AD, when based on engines’ serial 

numbers (s/n). On the other hand, 

applicability is extended for some engines 

that may have been fitted with certain 

crankcase s/n, supplied as spare parts. 

In addition, accomplishment instructions 

given through the relevant Service Bulletins 

(SB) have been detailed to better locate 

engine’s areas that are to be scrutinised. 

The aim of this AD is to ensure that the 

requested engine power is available at any 

time to prevent a sudden loss of power that 

could lead to a hazardous situation in a low 

altitude phase of flight. 

The MCAI requires inspecting certain 

crankcases for cracks and replacing the 

crankcase if cracks are found. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) Within the next 50 hours time-inservice (TIS) after the effective date of this 

AD, inspect the engine crankcase for cracks 

following Rotax Aircraft Engines Service 

Bulletin SB–912–029 R3, dated July 11, 2006. 

Repetitively thereafter do the inspection at 

each 100-hour, annual, or progressive 

inspection or within 110 hours TIS since last 

inspection, whichever occurs first. 

(2) If cracks in the engine crankcase are 

found during any inspection required by 

paragraph (f)(1) of this AD, before further 

flight, replace the crankcase following Rotax 

Aircraft Engines Service Bulletin SB–912– 

029 R3, dated July 11, 2006. 

(3) Installing a crankcase that has a S/N 

27812 or subsequent terminates the 

inspection requirements of paragraph (f)(1) of 

this AD. 

FAA AD Differences 

Note: This AD differs from the MCAI and/ 

or service information as follows: No 

differences. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Standards Office, 

FAA, has the authority to approve AMOCs 

for this AD, if requested using the procedures 

found in 14 CFR 39.19. Send information to 

ATTN: Sarjapur Nagarajan, Aerospace 

Engineer, FAA, Small Airplane Directorate,

sarjapur.nagarajan@faa.gov. Before using any 

approved AMOC on any airplane to which 

the AMOC applies, notify your appropriate 

principal inspector (PI) in the FAA Flight 

Standards District Office (FSDO), or lacking 

a PI, your local FSDO. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act 

(44 U.S.C. 3501 et. seq.), the Office of 

Management and Budget (OMB) has 

approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056. 

Special Flight Permit 

(h) We are limiting the special flight 

permits for this AD by the following 

conditions if the crankcase is cracked or 

there is evidence of oil leakage from the 

crankcase: 

(1) Perform a leak check as follows: 

(i) Clean the crankcase surface to remove 

any oil. 

(ii) Warm up the engine to a minimum oil 

temperature of 50 degrees C (120 degrees F). 

Information about warming up the engine 

can be found in the applicable line 

maintenance manual. 

(iii) Accelerate the engine to full throttle 

and stabilize at full throttle speed for a time 

period of 5 to 10 seconds. Information about 

performing a full throttle run can be found 

in the applicable line maintenance manual. 

(iv) Shutdown after running the engine at 

idle only long enough to prevent vapor locks 

in the cooling system and fuel system. 

(v) Inspect the crankcase for evidence of oil 

leakage. Oil wetting is permitted, but oil 

leakage of more than one drip in 3 minutes 

after engine shutdown is not allowed. 

(2) Check the crankcase mean pressure to 

confirm that it is 1.46 pounds-per-square 

inch gage (psig) (0.1 bar) or higher when 

checked at takeoff power to ensure proper 

return of oil from the crankcase to the oil 

tank. Information about checking crankcase 

mean pressure is available in the Lubrication 

System section of the applicable engine 

installation manual. 

(3) A ferry flight is not allowed if oil 

leakage exceeds one drip in 3 minutes or if 

crankcase mean pressure is below 1.46 psig.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Hawker Beechcraft Corporation Model 

390 airplanes. This proposed AD would 

require inspecting for installation of 

certain serial number (S/N) starter 

generators and replacing the starter 

generator if one with an affected serial 

number is found. This proposed AD 

results from reports that starter 

generators with deficient armature 

insulating materials may have been 

installed on certain airplanes. We are 

proposing this AD to detect and replace 

starter generators with defective 

armature insulating materials. This 

condition could result in the loss of 

operation of one or both starter 

generators with consequent loss of all 

non-battery electrical power. 

DATES: We must receive comments on 

this proposed AD by July 6, 2010. 

ADDRESSES: Use one of the following 

addresses to comment on this proposed 

AD:

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments 

regarding this proposed AD. Send your 

comments to an address listed under the 

ADDRESSES section. Include the docket 

number, ‘‘FAA–2010–0523; Directorate 

Identifier 2010–CE–018–AD’’ at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

the proposed AD. We will consider all 

comments received by the closing date 

and may amend the proposed AD in 

light 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 

concerning this proposed AD. 

Discussion 

We have received reports that certain 

serial number starter generators with 

deficient armature insulating materials 

may have been installed on Hawker 

Beechcraft Corporation Model 390 

airplanes. Starter generators with 

deficient armature fabrication may 

result in loss of operation of one or both 

starter generators in flight. 

This condition could result in the loss 

of operation of one or both starter 

generators with consequent loss of all 

non-battery electrical power. 

Relevant Service Information 

We have reviewed Hawker Beechcraft 

Mandatory Service Bulletin SB 24–3963, 

issued May 2009, and AMETEK 

Advanced Industries, Inc. Mandatory 

Service Bulletin—Number: 2009–0414, 

dated April 2009. 

The service information describes 

procedures for: 

• Inspection for starter generators 

with serial numbers that may have the 

deficient armature materials; and 

• Removal and replacement of starter 

generators with the affected serial 

numbers. 

FAA’s Determination and Requirements 

of the Proposed AD 

We are proposing this AD because we 

evaluated all information and 

determined the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. This proposed AD would 

require an inspection for suspect starter 

generators and their replacement if 

found. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 213 airplanes in the U.S. 

registry. 

We estimate the following costs to do 

the proposed inspection: 

Labor cost Parts cost Total cost per 

airplane 

Total cost on U.S. 

operators 

.5 work-hour × $85 per hour = $42.50 .............................................. Not applicable ............................. $42.50 $9,052.50 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

proposed inspection. We have no way of 

determining the number of airplanes 

that may need this replacement: 

Labor cost Parts cost Total cost per 

airplane 

10 work-hours (5 work-hours per side) × $85 per hour = $850 .............................. $4,069 per side = $8,138 ....................... $8,988 

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 regulation: 

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. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.
