AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

model IO–720–A1B Lycoming Engines 

reciprocating engines. This AD requires 

a crankshaft inspection for certain parts 

that may be installed. This AD was 

prompted by the failure of a crankshaft 

due to incorrect parts installed. We are 

issuing this AD to prevent engine 

crankshaft failure and damage to the 

airplane. 

DATES: This AD is effective September 

29, 2011. 

We must receive comments on this 

AD by October 31, 2011. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

SUPPLEMENTARY INFORMATION:

Discussion 

We received a report of a crankshaft 

failing after a repair station installed a 

crankshaft that had improper 

counterweight washers installed. The 

repair station has determined that two 

additional engines require inspection, to 

determine if the crankshaft they 

installed has the same improper 

washers. However, the two engines 

which have not been inspected, cannot 

be located. This condition, if not 

corrected, could result in engine 

crankshaft failure and damage to the 

airplane. 

FAA’s Determination 

We are issuing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist in 

other products of the same type design. 

AD Requirements 

This AD requires removing four 

cylinders from each affected engine and 

inspecting the engine crankshaft 

counterweight washers. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists 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 a crankshaft with improper 

damper washers installed, failed after 

440 hours of operation. The location of 

the two additional engines that require 

inspection, and the unknown current 

time-since-overhaul on those engines, 

warrants immediate notice to advise the 

current or subsequent owner of the need 

to inspect the engines before further 

flight. Therefore, we find that notice and 

opportunity for prior public comment 

are impracticable and that good cause 

exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety and 

was not preceded by notice and an 

opportunity for public comment. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include the docket number 

FAA–2011–0604 and Directorate 

Identifier 2011–NE–21–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. 

Costs of Compliance 

We estimate that this AD will affect 

two Lycoming Engines model IO–720– 

A1B reciprocating engines, installed on 

airplanes of U.S. registry. We also 

estimate that the inspection will take 

about 0.5 work-hour per engine to 

perform, and that the average labor rate 

is $85 per work-hour. Required parts 

would cost $0 per engine. Based on 

these figures, we estimate the total cost 

of the AD to U.S. operators to be $170. 

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.

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

2011–18–09 Lycoming Engines (formerly 

Textron Lycoming Division, AVCO 

Corporation): Amendment 39–16791; 

Docket No. FAA–2011–0604; Directorate 

Identifier 2011–NE–21–AD. 

Effective Date 

(a) This AD is effective September 29, 

2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Lycoming Engines 

reciprocating engines, model IO–720–A1B, 

serial number L–1457–54A and serial 

number L–1458–54A. These engines were 

last known to be installed in a Beech U–8F 

(Queen Air) N51779 and operating in the 

southern U.S. and Mexico. 

Unsafe Condition 

(d) This AD was prompted by the failure 

of a crankshaft due to incorrect parts 

installed. We are issuing this AD to prevent 

engine crankshaft failure and damage to the 

airplane. 

Compliance 

(e) Comply with this AD before further 

flight after the effective date of this AD, 

unless already done. 

Crankshaft Inspection 

(f) Remove the four cylinders from one side 

of the engine. Guidance on removing the 

cylinders can be found in the Lycoming 

Engines Overhaul Manual. 

(g) Each counterweight has two rollers that 

should be held in place by washers, 

Lycoming part number (P/N) 71907. The 

washers can be identified as having three 

holes each, with a diameter of 0.185 inch. 

These washers are located at the front and 

rear of each counterweight for a total of four 

P/N 71907 washers per counterweight. The 

eight counterweights are located at the top 

and bottom of each crankshaft cheek, totaling 

32 washers per crankshaft. 

(h) Rotate the crankshaft to inspect the 

holes in washers at the front and rear of each 

counterweight as well as the top and bottom 

of each cheek. 

(i) If each hole, in each of the 32 washers, 

measures 0.185 inch, then no further action 

is required. Reinstall the cylinders and test 

the engine. Guidance on reinstalling and 

testing can be found in the Lycoming Engines 

Overhaul Manual. 

(j) If any of the 32 washers have one or 

more holes that do not measure 0.185 inch, 

then remove the crankshaft assembly and 

replace it with a serviceable crankshaft 

assembly. Scrap the non-conforming 

crankshaft. 

Special Flight Permits 

(k) Special flight permits are authorized 

only if the engine has less than 400 hours 

time since overhaul. 

Alternative Methods of Compliance 

(AMOCs) 

(l) The Manager, New York Aircraft 

Certification Office, FAA, has the authority to 

approve AMOCs for this AD if requested 

using the procedures found in 14 CFR 39.19.
