Federal Register / Vol. 77, No. 39 / Tuesday, February 28, 2012 / Proposed Rules 11789 

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 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, I certify 

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); 

3. Will not affect intrastate aviation in 

Alaska to the extent that it justifies 

making a regulatory distinction; and 

4. 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 an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–600, 

–700, –700C, –800, –900, and –900ER 

series airplanes. This proposed AD was 

prompted by reports of flight crew 

failure to activate air data probe heat. 

This proposed AD would require 

modifying the anti-icing system for the 

angle of attack sensor, the total air 

temperature, and the pitot probes. We 

are proposing this AD to prevent ice 

from forming on air data system sensors 

and consequent loss of or misleading 

airspeed indication on all airspeed 

indicating systems, which could lead to 

loss of control of the airplane. 

DATES: We must receive comments on 

this proposed AD by April 13, 2012. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

The air data sensor heating system, 

when ON, heats the pitot probes that 

measure air pressure resulting from the 

airplane’s motion through the air in 

order to provide airspeed indications to 

the flight crew. This heating prevents 

ice from forming inside the pitot probes, 

which would degrade or block the 

probes’ ability to measure air pressure. 

The pitot heat switch, however, is not 

always set to ON. Although the existing 

ice protection system provides 

indication of activation to the flight 

crew, three reported incidents on Model 

737 airplanes were attributed to failure 

to activate the air data sensor heating 

system. The affected airplanes do not 

have an automatic activation of the air 

data sensor heating system; pilots 

activate the system manually as a 

pretakeoff checklist item. Failure to 

activate the air data sensor heating 

system could result in ice formation on 

air data system sensors, which could 

lead to misleading airspeed data or loss 

of all airspeed indicating systems, and 

loss of control of the airplane. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin 737–30A1063, dated November 

16, 2011. This service bulletin describes 

procedures for modifying the anti-icing 

system for the angle of attack sensor, the 

total air temperature, and the pitot 

probes. The modification involves the 

following: 

• Changing the wires and replacing 

the P5–9 window/pitot heat module on 

the P5 overhead panel in the flight 

compartment (the modified P5–9 

window/pitot heat module changes the 

current ON and OFF positions of the 

pitot heat switch to ON and AUTO); 

• Replacing two circuit breakers; 

installing relay supports, relays, and 

decals; and changing wiring at the P18 

circuit breaker panels in the flight 

compartment; and 

• Changing the wiring at the E2–2 

and E3–1 electronics shelves in the 

electrical/electronics compartment. 

These modifications to the air data 

sensor heating system provide 

automatic activation of the heating 

system when the modified pitot heat 

switch is set to AUTO and either engine 

is running. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 1,025 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Modification ................ 60 to 79 work-hours × $85 per hour = $5,100 

to $6,715.

$4,991 to $7,506 ........ Up to $14,221 ............ Up to $14,576,525. 

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 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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Model SAAB 2000 Airplanes. This 

proposed AD was prompted by reports 

that environmentally friendly de-icing 

agents used on certain electrical 

connectors and braids could cause 

corrosion damage. This proposed AD 

would require performing in certain 

locations a detailed inspection for 

corrosion of the electrical and 

electronics installation, and if corrosion 

is found repairing each affected harness 

braid or replacing each affected 

component and/or wiring harness. We 

are proposing this AD to detect and 

correct corrosion of critical system 

wiring, which could result in arcing 

and, in combination with other factors, 

a fire and consequent damage to the 

airplane. 

DATES: We must receive comments on 

this proposed AD by April 13, 2012.
