Airworthiness Directives; Teledyne

Continental Motors and Rolls-Royce,

plc O–200 Series Reciprocating

Engines

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment supersedes

two existing airworthiness directives

(AD’s), applicable to Teledyne

Continental Motors and Rolls-Royce, plc

O–200 series reciprocating engines, that

currently require resetting engine timing

to 24° Before Top Center (BTC). This

amendment returns to the 28° BTC

engine timing for those engines

equipped with improved cylinders that

have strengthened heads. In addition,

this amendment drops the TCM O–200C

model which never went into

production. This amendment is

prompted by the availability of

improved cylinders. The actions

specified by this AD are intended to

prevent possible cylinder cracking with

subsequent loss of engine power.

DATES: Effective July 18, 1996.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of July 18,

1996.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39)

by superseding airworthiness directive

(AD) 77–13–03, Amendment 39–2925

(42 FR 31770, June 23, 1977), which is

applicable to Teledyne Continental

Motors (TCM) O–200A, O–200B, was

published in the Federal Register on

June 15, 1995 (60 FR 31421). That action

proposed to retain the 24° before top

center (BTC) engine timing for engines

with cylinders that have part number

(P/N) lower than 641917; allow the

return to 28° BTC engine timing for

those engines with cylinder P/N 641917

and subsequent (higher) part numbers,

restamp the engine data plate to indicate

engine timing of 28° BTC; and drop the

TCM O–200C series engines from the

AD’s applicability. The actions must be

accomplished in accordance with TCM

Service Bulletin (SB) No. SB94–8, dated

September 14, 1994.

This AD also supersedes AD 78–19–

02, Amendment 39–3301 (43 FR 41374,

September 18, 1978), applicable to

Rolls-Royce, plc (R–R) O–200A, O–

200B, and O–200C series engines, which

also requires resetting the engine timing

to 24°. This AD combines the TCM

applicability of AD 77–13–03 with the

R–R applicability of AD 78–19–02 into

one, superseding AD.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment.

One commenter (the manufacturer)

states that the timing adjustment may be

set to the limits of (+1°, ¥1°). The

NPRM incorrectly limited the timing

adjustment to (+1°, ¥0°). The FAA

concurs and has revised this final rule

accordingly.

After careful review of the available

data, including the comments noted

above, the FAA has determined that air

safety and the public interest require the

adoption of the rule with the changes

described previously. The FAA has

determined that these changes will

neither increase the economic burden

on any operator nor increase the scope

of the AD.

The FAA estimates that 23,500

engines installed on aircraft of U.S.

registry will be affected by this AD, that

it will take approximately 2 work hours

per engine to accomplish the required

actions, and that the average labor rate
29932 Federal Register / Vol. 61, No. 115 / Thursday, June 13, 1996 / Rules and Regulations

is $60 per work hour. This AD adds no

additional requirements; the resetting of

engine timing for engines with the

improved cylinders is optional.

Therefore, there is no cost imposed by

the required actions. However, if the

timing was reset on all applicable

engines, based on these figures, the total

cost impact of the AD on U.S. operators

is estimated to be $2,820,000.

The regulations adopted herein will

not have substantial direct effects 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. Therefore, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

For the reasons discussed above, I

certify that this action (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); 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. A final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

Note: This airworthiness directive (AD)

applies to each engine identified in the

preceding applicability provision, regardless

of whether it has been modified, altered, or

repaired in the area subject to the

requirements of this AD. For engines that

have been modified, altered, or repaired so

that the performance of the requirements of

this AD is affected, the owner/operator must

use the authority provided in paragraph (g)

to request approval from the Federal Aviation

Administration (FAA). This approval may

address either no action, if the current

configuration eliminates the unsafe

condition, or different actions necessary to

address the unsafe condition described in

this AD. Such a request should include an

assessment of the effect of the changed

configuration on the unsafe condition

addressed by this AD. In no case does the

presence of any modification, alteration, or

repair remove any engine from the

applicability of this AD.

Compliance: Required as indicated, unless

accomplished previously.

To prevent possible cylinder cracking with

subsequent loss of engine power, accomplish

the following:

(a) For engines that have one or more

cylinders with part numbers (P/N) lower than

641917, within the next 50 hours time in

service (TIS) after the effective date of this

AD, reset the engine timing to 24° (+1°, ¥1°)

Before Top Center (BTC) on both magnetos in

accordance with the magneto to engine

timing procedure for direct drive engines in

TCM Service Bulletin (SB) No. SB94–8, dated

September 14, 1994.

(b) For engines that have all four cylinders

with P/N 641917 or higher, the engine timing

may be reset to 28° (+1°, ¥1°) BTC on both

magnetos in accordance with the magneto

engine timing procedure for direct drive

engines in TCM SB No. SB94–8, dated

September 14, 1994.

(c) Subsequent installation of cylinders

must be of the P/N listed in paragraph (b) of

this AD to retain the 28° BTC timing.

Note: The P/N is stamped on the cylinder

barrel flange.

(d) This AD supersedes AD 77–13–03 and

AD 78–19–02.

(e) When paragraph (a) is accomplished,

restamp the engine data plate to indicate

magneto timing of 24° BTC.

(f) When paragraph (b) is accomplished,

restamp the engine data plate to indicate

magneto timing of 28° BTC.
