AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Raytheon Model Hawker 800XP 

airplanes. This proposed AD would 

require inspecting to determine if the 

correct fuse is installed on the hydraulic 

over-temperature switch on panel ZK in 

the rear equipment bay, and replacing 

the existing fuse if necessary. This 

proposed AD results from a report of the 

installation of an incorrect fuse on the 

over-temperature switch on panel ZK in 

the rear equipment bay during airplane 

maintenance. We are proposing this AD 

to prevent a short circuit in the fuse and 

consequent heat damage to associated 

wiring and surrounding equipment, 

which could result in smoke or fire on 

the airplane. 

DATES: We must receive comments on 

this proposed AD by December 12, 

2005.

Discussion 

We have received a report of the 

installation of an incorrect fuse on the 

over-temperature switch on panel ZK in 

the rear equipment bay on Raytheon 

Model Hawker 800XP airplanes. The 

manufacturer indicated that, during 

airplane maintenance, a 20-amp fuse, 

instead of the required 3-amp fuse, may 

have inadvertently been installed on 

fuse F1 of the ZK panel. This condition, 

if not corrected, could result in a short 

circuit in the fuse and consequent heat 

damage to associated wiring and 

surrounding equipment, which could 

result in smoke or fire on the airplane. 

Relevant Service Information 

We have reviewed Raytheon Service 

Bulletin SB 24–3724, dated May 2005. 

The service bulletin describes 

procedures for inspecting to determine 

if a 20-amp fuse is installed on the 

hydraulic over-temperature switch on 

panel ZK in the rear equipment bay, and 

replacing any 20-amp fuse with a 3-amp 

fuse. The service bulletin also 

recommends reporting compliance with 

the service bulletin and contacting the 

manufacturer if signs of damage are 

found on associated terminals and 

wires. 

FAA’s Determination and Requirements 

of the Proposed AD 

We have evaluated all pertinent 

information and identified an unsafe 

condition that is likely to exist or 

develop on other airplanes of this same 

type design. For this reason, we are 

proposing this AD, which would require 

accomplishing the actions specified in 

the service information described 

previously, except as discussed under 

‘‘Differences Between the Proposed AD 

and Service Bulletin.’’ 

Differences Between the Proposed AD 

and Service Bulletin 

Where the service bulletin specifies 

contacting the manufacturer if any sign 

Federal Register / Vol. 70, No. 207 / Thursday, October 27, 2005 / Proposed Rules 61915 

of damage is found on associated 

terminals and wires, this proposed AD 

would require that, before further flight, 

you must contact the FAA for applicable 

repair actions. Then, before further 

flight, accomplish the applicable repair 

actions specified by the FAA in 

accordance with a method approved by 

the FAA. 

Although the Accomplishment 

Instructions of the service bulletin 

describe procedures for reporting 

compliance with the service bulletin, 

this proposed AD would not require that 

action. 

The service bulletin refers only to an 

‘‘inspection’’ to ensure that a 20-amp 

fuse is not installed. We have 

determined that the procedures in the 

service bulletin should be described as 

a ‘‘general visual inspection.’’ Note 1 

has been included in this proposed AD 

to define this type of inspection. 

Clarification of Service Bulletin Note 

The Raytheon service bulletin 

includes a note in the Accomplishment 

Instructions to inform operators to 

contact Raytheon ‘‘should any difficulty 

be encountered’’ in accomplishing the 

service bulletin. We have included Note 

2 in this proposed AD to clarify that any 

deviation from the instructions 

provided in the service bulletin must be 

approved as an alternative method of 

compliance under paragraph (g) of this 

proposed AD. 

Costs of Compliance 

There are about 138 airplanes of the 

affected design in the worldwide fleet. 

This proposed AD would affect about 

110 airplanes of U.S. registry. The 

proposed actions would take about 2 

work hours per airplane, at an average 

labor rate of $65 per work hour. 

Required parts cost is negligible. Based 

on these figures, the estimated cost of 

the proposed AD for U.S. operators is 

$14,300, or $130 per airplane. 

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. See the ADDRESSES section 

for a location to examine the regulatory 

evaluation. 

List of Subjects in 14 CFR Part 39

safety, Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 Federal Aviation 

Administration (FAA) amends § 39.13 

by adding the following new 

airworthiness directive (AD): 

Raytheon Aircraft Company: Docket No. 

FAA–2005–22749; Directorate Identifier

hydraulic over-temperature switch on panel 

ZK in the rear equipment bay in accordance 

with the Accomplishment Instructions of 

Raytheon Service Bulletin SB 24–3724, dated 

May 2005. If a 20-amp fuse is installed, 

before further flight, replace with a 3-amp 

fuse in accordance with the Accomplishment 

Instructions of the service bulletin. 

Note 1: For the purposes of this AD, a 

general visual inspection is: ‘‘A visual 

examination of an interior or exterior area, 

installation, or assembly to detect obvious 

damage, failure, or irregularity. This level of 

inspection is made from within touching

may be necessary to enhance visual access to 

all exposed surfaces in the inspection area. 

This level of inspection is made under 

normally available lighting conditions such 

as daylight, hangar lighting, flashlight, or 

droplight and may require removal or 

opening of access panels or doors. Stands, 

ladders, or platforms may be required to gain 

proximity to the area being checked.’’

Note 2: A note in the Accomplishment 

Instructions of the Raytheon service bulletin 

instructs operators to contact Raytheon if any 

difficulty is encountered in accomplishing 

the service bulletin. However, any deviation 

from the instructions provided in the service 

bulletin must be approved as an alternative 

method of compliance (AMOC) under 

paragraph (g) of this AD. 

Repair Approval 

(g) Where the Raytheon Service Bulletin SB 

24–3724, dated May 2005, says to contact the

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

BAE Systems (Operations) Limited 

Model BAe 146–100A and –200A series 

airplanes. This proposed AD would 

require inspecting the nose landing gear 

(NLG) assembly to determine the part 

number of the NLG main fitting 

subassembly. For subject NLG main 

fitting subassemblies, this proposed AD 

would also require determining the total 

number of accumulated landings on a 

subject NLG main fitting subassembly, 

and eventually replacing the NLG 

assembly. This proposed AD results 

from a report indicating that the 

airplane maintenance manual contains 

incorrect safe-life limit information for 

certain NLG assemblies. We are 

proposing this AD to ensure that 

affected NLG fitting subassemblies are 

removed from service before they reach 

their approved safe-life limit. Operating 

with an NLG fitting subassembly that is 

beyond its approved safe-life limit could 

result in failure of the NLG and 

consequent loss of directional control 

on the ground and major structural 

damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by November 28, 

2005.

Discussion 

The Civil Aviation Authority (CAA), 

which is the airworthiness authority for 

the United Kingdom, notified us that an 

unsafe condition may exist on all BAE 

Systems (Operations) Limited Model 

BAe 146–100A and –200A series 

airplanes. The CAA advises that Chapter 

5 of the airplane maintenance manual 

(AMM) may contain incorrect safe-life 

limit information for certain nose 

landing gear (NLG) assemblies. 

Operating with an NLG fitting 

subassembly that is beyond its approved 

safe-life limit could lead to fatigue 

cracking of the main fitting of the NLG. 

This condition, if not corrected, could 

result in failure of the NLG and 

consequent loss of directional control 

on the ground and major structural 

damage to the airplane. 

Relevant Service Information 

BAE Systems has issued Service 

Bulletin ISB.32–169, dated October 4, 

2004. The service bulletin describes 

procedures for inspecting the NLG 

assembly to determine the part number 

of the NLG main fitting subassembly. If 

a subassembly having a subject part 

number is installed, the service bulletin 

specifies determining the total 

accumulated landings on the 

subassembly (since it was new or 

overhauled); eventually replacing the 

NLG assembly with a new, serviceable, 

or overhauled NLG assembly; and 

returning the replaced NLG assembly to 

Messier-Dowty or an overhaul facility. 

(For the purposes of this proposed AD, 

a serviceable NLG is one on which the 

part number of the NLG main fitting 

subassembly has been identified and the 

number of landings has been 

determined if necessary.) 

Accomplishing the actions specified in
