We

are issuing

this

AD because we evaluated

all information

provided

by EASA

and determined

the unsafe condition exists

and

is

l

i kely

to exist

or deve

l op on

other products

of the same

type design.

This

AD requires inspection

ofthe engine

PT disk

and,

if found damaged,

its rep

l acement

with

a part

e

l igible

for insta

ll ation. F A A's

D ete rmin

f th e E

ff ec

ti ve

D ate No domestic

operators

use

this product. Therefore,

we find

that notice

and opportunity

for prior public comment

are unnecessary

and

that good

cause

exists

for making

this amendment

effective

in less

than

30 days. Costs

of Co

m

p

li

a

n ce We estimate

that

this

AD affects

0 engines

installed

on airplane

s of U.S. registry. We

also estimate

that

it will

take about

60 hours

per engine

to do the inspection

required by this

AD.

The average

labor

rate

is $85

per hour.

Based

on these figures

, we estimate the total

cost

of the

AD

to U.S. operators

to

be

$0. Aut
