Airworthiness Directives; Hawker 

Beechcraft Corporation (Type 

Certificate Previously Held by 

Raytheon Aircraft Company) Models 

B300 and B300C Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Hawker Beechcraft Corporation (type 

certificate previously held by Raytheon 

Aircraft Company) Models B300 and 

B300C airplanes. This AD requires you 

to inspect the terminal board on the 

circuit card rack assembly to determine 

if the correct bus bar is installed and 

replace if necessary. This AD also 

requires you to do an operational check 

of the left and right pitot heat 

annunciators for proper operation and 

take corrective action as necessary. This 

AD results from reports of the left and 

right pitot heat annunciators not 

illuminating for an inoperative pitot 

heat condition. We are issuing this AD 

to detect and correct installation of an 

incorrect bus bar, which could result in 

failure of the pitot heat annunciators to 

illuminate. This failure could lead to the 

pilot being unaware that moisture has 

frozen on the pitot tube(s) and cause 

erroneous flight instrument indication. 

DATES: This AD becomes effective on 

April 8, 2010. 

On April 8, 2010, the Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

On December 8, 2009, we issued a 

proposal to amend part 39 of the Federal 

Aviation Regulations (14 CFR part 39) to 

include an AD that would apply to 

certain Hawker Beechcraft Corporation 

Models B300 and B300C airplanes. This 

proposal was published in the Federal 

Register as a notice of proposed 

rulemaking (NPRM) on December 17, 

2009 (74 FR 66924). The NPRM 

proposed to require inspecting the 

terminal board on the circuit card rack 

assembly to determine if the correct bus 

bar is installed and replacing if 

necessary. The NPRM also proposed to 

require doing an operational check of 

the left and right pitot heat annunciators 

for proper operation and taking 

corrective action as necessary. 

Comments 

We provided the public the 

opportunity to participate in developing 

this AD. We received no comments on 

the proposal or on the determination of 

the cost to the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed except for 

minor editorial corrections. We have 

determined that these minor 

corrections: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Costs of Compliance 

We estimate that this AD will affect 

131 airplanes in the U.S. registry. 

We estimate the following costs to do 

the operational check: 

Labor cost Parts cost Total cost 

per airplane 

Total cost 

on U.S. 

operators 

1 work-hour × $85 per hour = $85 ................................................................. Not applicable .................................... $85 $11,135 

We estimate the following costs to do 

any necessary placard fabrication and 

installation that will be required based 

on the results of the operational check. 

We have no way of determining the 

number of airplanes that may need the 

placard:

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 AD. 

Regulatory Findings 

We have determined that 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 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 summary of the costs 

to comply with this AD (and other 

information as included in the 

Regulatory Evaluation) and placed it in 

the AD Docket. You may get a copy of 

this summary by sending a request to us 

at the address listed under ADDRESSES. 

Include ‘‘Docket No. FAA–2009–1180; 

Directorate Identifier 2009–CE–060–AD’’ 

in your request.

Subject 

(d) Air Transport Association of America 

(ATA) Code 31: Instruments. 

Unsafe Condition 

(e) This AD results from reports of the left 

and right pitot heat annunciators not 

illuminating for an inoperative pitot heat 

condition. We are issuing this AD to detect 

and correct the installation of an incorrect 

bus bar, which could result in failure of the 

pitot heat annunciators to illuminate. This 

failure could lead to moisture freezing on the 

pitot tube(s) and cause erroneous flight 

instrument indication. 

Compliance 

(f) To address this problem, you must do 

the following, unless already done: 

Actions Compliance Procedures 

(1) Do an operational check of the left and right 

pitot heat annunciators for illumination.

Within the next 15 hours time-in-service (TIS) 

after April 8, 2010 (the effective date of this 

AD) or within the next 30 days after April 8, 

2010 (the effective date of this AD), whichever occurs first.

Follow Hawker Beechcraft Mandatory Service 

Bulletin SB 31–3948, Issued: April 2009. 

(2) If the left and/or right pitot heat annunciators 

do not illuminate, install a placard on the instrument panel within the pilot’s clear view 

specifying the pitot heat annunciator(s) as inoperative.

Before further flight after the operational 

check required in paragraph (f)(1) of this 

AD.

Follow Hawker Beechcraft Mandatory Service 

Bulletin SB 31–3948, Issued: April 2009. 

(3) Inspect the terminal board on the circuit 

card rack assembly to determine if a five-hole 

bus bar is installed.

Within the next 50 hours TIS after April 8, 

2010 (the effective date of this AD) or within the next 3 months after April 8, 2010 (the 

effective date of this AD), whichever occurs 

first.

Follow Hawker Beechcraft Mandatory Service 

Bulletin SB 31–3948, Issued: April 2009. 

(4) If a five-hole bus bar is found installed during the inspection required in paragraph (f)(3) 

of this AD, perform an operational check. If 

the operational check detects anomalies, 

contact the manufacturer specified in paragraph (i)(2) of this AD to obtain an FAA-approved repair scheme and incorporate the repair scheme.

Before further flight after the inspection required in paragraph (f)(3) of this AD.Follow Hawker Beechcraft Mandatory Service 

Bulletin SB 31–3948, Issued: April 2009. 

(5) If a four-hole bus bar is found installed during the inspection required in paragraph (f)(3) 

of this AD, replace it with a five-hole bus bar 

and perform an operational check. If the 

operational check detects anomalies, contact 

the manufacturer specified in paragraph (i)(2) 

of this AD to obtain an FAA-approved repair 

scheme and incorporate the repair scheme.

Before further flight after the inspection required in paragraph (f)(3) of this AD.Follow Hawker Beechcraft Mandatory Service

heat annunciators is verified in paragraphs 

(f)(4) and (f)(5) of this AD, remove the 

placard that was installed in paragraph (f)(2) 

of this AD.

Before further flight after doing the operational 

check required in paragraphs (f)(4) and 

(f)(5) of this AD.

Follow Hawker Beechcraft Mandatory Service 

Bulletin SB 31–3948, Issued: April 2009. 

Note: The operational check required in 

this AD is different from the pilot’s pre-flight 

check. An FAA-approved licensed mechanic 

authorized to do maintenance is required to 

do the operational check. 

(g) The inspection action of paragraph (f)(3) 

of this AD and the follow-on actions of 

paragraphs (f)(4) and (f)(5) of this AD may be 

done instead of the operational check and the 

placard requirements of paragraphs (f)(1) and 

(f)(2) of this AD provided the inspection is 

done within the next 15 hours TIS after April 

8, 2010 (the effective date of this AD).
