Discussion 

The Direction Ge ́ne ́rale de l’Aviation 

Civile (DGAC), which is the 

5768 Federal Register / Vol. 69, No. 25 / Friday, February 6, 2004 / Proposed Rules 

airworthiness authority for France, 

notified the FAA that an unsafe 

condition may exist on certain Model 

Fan Jet Falcon series airplanes and 

Model Mystere-Falcon 20 series 

airplanes. The DGAC advises that 

cracking has been found in the vertical 

posts of window frames in the flight 

compartment that were not included in 

the maintenance program inspection 

area. The airplane manufacturer, 

Dassault Aviation, has revised certain 

work cards in the maintenance manual 

to include procedures for inspecting and 

testing these window frames. Cracking 

of the window frames could result in 

rapid depressurization of the fuselage 

and consequent reduced structural 

integrity of the airplane. 

Explanation of Relevant Service 

Information 

Dassault has issued revised Work 

Card 53–30–07, ‘‘Non-Destructive 

Ultrasonic Testing of Vertical Posts on 

Screw-Mounted Windows’’ of the 

Dassault Aviation Fan Jet Falcon 

Maintenance Manual, dated November 

2001. The work card describes 

procedures for testing (including 

calibrating the equipment) the posts of 

the window frames in the flight 

compartment, including the right side 

window, left and right rear windows, 

front window, and pilot and co-pilot 

windows, for stress corrosion cracking. 

Dassault has also issued revised Work 

Card 53–30–12, ‘‘Endoscopic Inspection 

of the Frames of Pilot, Co-Pilot, and 

Front Glass Panels (Aircraft Not 

Changed Per SB No. 701)’’ of the 

Dassault Aviation Fan Jet Falcon 

Maintenance Manual, dated November 

2001. The work card describes 

procedures for using an endoscope and 

inspecting the window frames of the 

pilot, co-pilot, and front windows in the 

flight compartment for stress corrosion 

and subsequent cracking. 

Accomplishment of the actions 

specified in the service information is 

intended to adequately address the 

identified unsafe condition. The DGAC 

classified this service information as 

mandatory and issued French 

airworthiness directive 2001–600–

028(B), dated December 12, 2001, to 

ensure the continued airworthiness of 

these airplanes in France. 

FAA’s Conclusions 

These airplane models are 

manufactured in France and are type 

certificated for operation in the United 

States under the provisions of section 

21.29 of the Federal Aviation 

Regulations (14 CFR 21.29) and the 

applicable bilateral airworthiness 

agreement. Pursuant to this bilateral 

airworthiness agreement, the DGAC has 

kept the FAA informed of the situation 

described above. The FAA has 

examined the findings of the DGAC, 

reviewed all available information, and 

determined that AD action is necessary 

for products of this type design that are 

certificated for operation in the United 

States. 

Explanation of Requirements of 

Proposed AD 

Since an unsafe condition has been 

identified that is likely to exist or 

develop on other airplanes of the same 

type design registered in the United 

States, the proposed AD would require 

accomplishment of the actions specified 

in the service information described 

previously. This proposed AD also 

includes a reporting requirement. 

Difference Between the Proposed AD 

and the French Airworthiness Directive 

The French airworthiness directive is 

applicable to ‘‘all Fan Jet Falcon and 

Mystere Falcon 20-(x)5 aircraft, all serial 

numbers.’’ The applicability of this 

proposed AD is ‘‘Model Fan Jet Falcon 

series airplanes and Model MystereFalcon 20 series airplanes; certificated 

in any category; except those which 

have incorporated Dassault Service 

Bulletin AMD–BA FJF–701, Revision 1, 

dated October 22, 1987.’’ This exception 

appears in Dassault Aviation Work Card 

53–30–12, titled ‘‘Endoscopic 

Inspection of the Frames of Pilot, CoPilot, and Front Glass Panels (Aircraft 

Not Changed Per SB No. 701),’’ of the 

Dassault Aviation Fan Jet Falcon 

Maintenance Manual, dated November 

2001. This difference has been 

coordinated with the DGAC. 

Cost Impact 

The FAA estimates that 220 airplanes 

of U.S. registry would be affected by this 

proposed AD, that it would take 

approximately 4 work hours per 

airplane to accomplish the proposed 

actions, and that the average labor rate 

is $65 per work hour. Based on these 

figures, the cost impact of the proposed 

AD on U.S. operators is estimated to be 

$57,200, or $260 per airplane. 

The cost impact figure discussed 

above is based on assumptions that no 

operator has yet accomplished any of 

the proposed requirements of this AD 

action, and that no operator would 

accomplish those actions in the future if 

this AD were not adopted. The cost 

impact figures discussed in AD 

rulemaking actions represent only the 

time necessary to perform the specific 

actions actually required by the AD. 

These figures typically do not include 

incidental costs, such as the time 

required to gain access and close up, 

planning time, or time necessitated by 

other administrative actions.

Regulatory Impact 

The regulations proposed herein 

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. Therefore, 

it is determined that this proposal 

would not have federalism implications 

under Executive Order 13132. 

For the reasons discussed above, I 

certify that this 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) if 

promulgated, 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 copy of the draft 

regulatory evaluation prepared for this 

action is contained in the Rules Docket. 

A copy of it may be obtained by 

contacting the Rules Docket at the 

location provided under the caption
