Airworthiness Directives; The Boeing 

Company Model 737–100, –200, –200C, 

–300, –400, and –500 Series Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD would require installing an 

automatic shutoff system for the center 

and auxiliary tank fuel boost pumps, as 

applicable, and installing a placard in 

the airplane flight deck if necessary; 

replacing the P5–2 fuel system module 

assembly; and installing the uncommanded on (UCO) protection 

system for the center and auxiliary tank 

fuel boost pumps, as applicable. This 

proposed AD would also require 

revisions to the Limitations and Normal 

Procedures sections of the airplane 

flight manual to advise the flightcrew of 

certain operating restrictions for 

airplanes equipped with an automatic 

shutoff system. This proposed AD 

would also require revising the 

maintenance program by incorporating 

new airworthiness limitations for fuel 

tank systems to satisfy Special Federal 

Aviation Regulation No. 88 

requirements. This proposed AD was 

prompted by fuel system reviews 

conducted by the manufacturer. We are 

proposing this AD to prevent operation 

of the center and auxiliary tank fuel 

boost pumps with continuous low 

pressure, which could lead to friction 

sparks or overheating in the fuel pump 

inlet that could create a potential 

ignition source inside the center and 

auxiliary fuel tanks. These conditions, 

in combination with flammable fuel 

vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by November 28, 

2011. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The FAA has examined the 

underlying safety issues involved in fuel 

tank explosions on several large 

transport airplanes, including the 

adequacy of existing regulations, the 

service history of airplanes subject to 

those regulations, and existing 

maintenance practices for fuel tank 

systems. As a result of those findings, 

we issued a regulation titled ‘‘Transport 

Airplane Fuel Tank System Design 

Review, Flammability Reduction and 

Maintenance and Inspection 

Requirements’’ (66 FR 23086, May 7, 

2001). In addition to new airworthiness 

standards for transport airplanes and 

new maintenance requirements, this 

rule included Special Federal Aviation 

Regulation No. 88 (‘‘SFAR 88,’’ 

Amendment 21–78, and subsequent 

Amendments 21–82 and 21–83). 

Among other actions, SFAR 88 

requires certain type design (i.e., type 

certificate (TC) and supplemental type 

certificate (STC)) holders to substantiate 

that their fuel tank systems can prevent 

ignition sources in the fuel tanks. This 

requirement applies to type design 

holders for large turbine-powered 

transport airplanes and for subsequent 

modifications to those airplanes. It 

requires them to perform design reviews 

and to develop design changes and 

maintenance procedures if their designs 

do not meet the new fuel tank safety 

standards. As explained in the preamble 

to the rule, we intended to adopt 

airworthiness directives to mandate any 

changes found necessary to address 

unsafe conditions identified as a result 

of these reviews. 

In evaluating these design reviews, we 

have established four criteria intended 

to define the unsafe conditions 

associated with fuel tank systems that 

require corrective actions. The 

percentage of operating time during 

which fuel tanks are exposed to 

flammable conditions is one of these 

criteria. The other three criteria address 

the failure types under evaluation: 

single failures, single failures in 

combination with a latent condition(s), 

and in-service failure experience. For all 

four criteria, the evaluations included 

consideration of previous actions taken 

that may mitigate the need for further 

action. 

We have determined that the actions 

identified in this AD are necessary to 

reduce the potential of ignition sources 

inside fuel tanks, which, in combination 

with flammable fuel vapors, could result 

in fuel tank explosions and consequent 

loss of the airplane. 

The manufacturer has found that 

certain failures will result in the center 

and auxiliary tank fuel boost pumps 

continuing to run after the tank has been 

depleted. Depending on the failure, 

pump low pressure may not be 

annunciated, or power may not be 

removed from the pump when the 

pump has been commanded ‘‘OFF.’’ 

Operation of the center and auxiliary 

tank fuel boost pumps with continuous 

low pressure could lead to friction 

sparks or overheating in the fuel pump 

inlet. This condition, if not corrected, 

could result in a fuel tank explosion and 

consequent loss of the airplane. 

Relevant Service Information 

We have reviewed Boeing Alert 

Service Bulletin 737–28A1216, Original 

Issue, dated July 29, 2010, which 

describes procedures for installing the 

automatic shutoff system for the center 

and auxiliary fuel tank boost pumps, as 

applicable, on Model 737–300, –400, 

and –500 series airplanes; and refers to 

Airworthiness Limitation (AWL) No. 

28–AWL–20 and No. 28–AWL–21 that 

are related to the modifications 

specified in that service bulletin. 

We have also reviewed Boeing Alert 

Service Bulletin 737–28A1228, Original 

Issue, dated August 2, 2010, which 

describes procedures for installing the 

automatic shutoff system for the center 

and auxiliary fuel tank boost pumps, as 

applicable, on Model 737–100, –200, 

and –200C series airplanes; and refers to 

AWL No. 28–AWL–21 and AWL No. 

28–AWL–22 that are related to the 

modifications specified in that service 

bulletin. 

Boeing Alert Service Bulletins 737– 

28A1216, Original Issue, dated July 29, 

2010; and 737–28A1228, Original Issue, 

dated August 2, 2010; specify prior or 

concurrent accomplishment of Boeing 

Service Bulletin 737–28A1210, Original 

Issue, dated August 2, 2010, which 

describes procedures for replacing the 

P5–2 fuel system module assembly with 

a new or modified P5–2 fuel system 

module assembly having a new part 

number, for Model 737–100, –200, 

–200C, –300, –400, and –500 series 

airplanes. 

Boeing Service Bulletin 737– 

28A1210, Original Issue, dated August 

2, 2010, refers to BAE Systems Service 

Bulletin 69–37335–28–04, Revision 2, 

dated February 10, 2010, as an 

additional source of guidance for 

modifying and updating the existing 

P5–2 fuel system module assembly part 

numbers to new part numbers. 

We have also reviewed Boeing Alert 

Service Bulletin 737–28A1227, Revision 

1, dated July 18, 2011. The service 

information describes procedures for 

installing the ‘‘un-commanded ON’’ 

protection system for the center and 

auxiliary fuel boost pumps, as 

applicable, on airplanes. The 

installation includes installing new 

relays and toggle switches in the J2802 

box assembly located in the electronic 

equipment bay (E/E bay), and changing 

and adding new wire bundles that route 

from the J2802 box assembly to the P5 

forward overhead panel and the P6 

disconnect panels. This service bulletin 

also refers to AWL No. 28–AWL–24 and 

No. 28–AWL–25 that are related to the 

modifications specified in that service 

bulletin for Model 737–100, –200, and 

–200C series airplanes; and AWL No. 

28–AWL–23 and No. 28–AWL–24 that 

are related to the modifications 

specified in that service bulletin for 

Model 737–300, –400, and –500 

airplanes. 

We have also reviewed Section C, 

‘‘Fuel Systems Airworthiness 

Limitations,’’ of Section 9 of the Boeing 

737–100/200/200C/300/400/500 

Airworthiness Limitations (AWLs) and 

Certification Maintenance Requirements 

(CMRs), Document D6–38278–CMR, 

Revision July 2011, which contains the 

following airworthiness limitations: 

• For Model 737–300, –400, and –500 

series airplanes that have incorporated 

Boeing Alert Service Bulletin 737– 

28A1216, AWLs No. 28–AWL–20 and 

No. 28–AWL–21 are airworthiness 

limitation instructions (ALIs) for an 

operational check of the installed 

automatic shutoff system. 

• For Model 737–100, –200, and 

–200C series airplanes that have 

incorporated Boeing Alert Service 

Bulletin 737–28A1228, AWLs No. 28– 

AWL–21 and No. 28–AWL–22 are ALIs 

for an operational check of the installed 

automatic shutoff system. 

• For Model 737–300, –400, and –500 

series airplanes that have incorporated 

Boeing Alert Service Bulletin 737– 

28A1227, AWLs No. 28–AWL–23 and

• For Model 737–100, –200, and 

–200C series airplanes that have 

incorporated Boeing Alert Service 

Bulletin 737–28A1227, AWL No. 28– 

AWL–24 and No. 28–AWL–25 are ALIs 

for an operational check of the installed

Other Relevant Rulemaking 

On April 18, 2001, we issued AD 

2001–08–24, Amendment 39–12201 (66 

FR 20733, April 25, 2001), for all Model 

737 series airplanes. That AD requires 

revising the airplane flight manual to 

prohibit extended dry operation of the 

center tank fuel pumps (with no fuel 

passing through the pumps). We issued 

that AD to prevent ignition of fuel 

vapors due to the generation of sparks 

and a potential ignition source inside 

the center tank caused by metal-to-metal 

contact during dry fuel pump operation, 

which could result in a fire or explosion 

of the fuel tank. Accomplishment of the 

actions required by paragraphs (g), (h), 

(i), and (l) of this AD, and paragraph (j) 

or (k) of this AD, as applicable, is 

acceptable for compliance with the 

requirements of paragraph (a) of AD 

2001–08–24. 

On December 16, 2009, we issued AD 

2008–10–09 R1, Amendment 39–16148 

(74 FR 69264, December 31, 2009), for 

all Model 737–100, –200, –200C, –300, 

–400, and –500 series airplanes. That 

AD requires revising the maintenance 

program to incorporate new 

airworthiness limitations (AWLs) for 

fuel tank systems to satisfy Special 

Federal Aviation Regulation No. 88 

requirements. That AD also requires an 

initial inspection to phase in certain 

repetitive AWL inspections, and repair 

if necessary. We issued that AD to 

prevent the potential for ignition 

sources inside fuel tanks caused by 

latent failures, alterations, repairs, or 

maintenance actions, which, in 

combination with flammable fuel 

vapors, could result in a fuel tank 

explosion and consequent loss of the 

airplane. Incorporation of AWLs No. 

28–AWL–21 and No. 28–AWL–22 for 

Model 737–100, –200, and 200C series 

airplanes; and AWLs No. 28–AWL–20 

and No. 28–AWL–21 for Model 737– 

300, –400, and –500 series airplanes; in 

accordance with paragraphs (g)(1) and 

(g)(2) of AD 2008–10–09 R1, terminates 

the requirements of the corresponding 

AWLs incorporation required by 

paragraph (l) of this AD. 

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 these same 

type designs. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously, except as discussed under 

‘‘Differences Between the Proposed AD 

and the Service Information.’’ 

This proposed AD would also require 

installing a placard adjacent to the 

pilot’s primary flight display on all 

airplanes not equipped with an 

automatic shutoff system for the center 

tank fuel boost pumps and auxiliary fuel 

boost pumps, to specify that fuel usage 

restrictions given in AD 2001–08–24 (66 

FR 20733, April 25, 2001) are required. 

Installing an automatic shutoff system 

on an airplane would end the need for 

the placard installation for only that 

airplane. 

This proposed AD would also require 

revisions to the Limitations and Normal 

Procedures sections of the applicable 

Boeing 737 Airplane Flight Manual 

(AFM) to advise the flightcrew of certain 

operating restrictions related to the 

automatic shutoff system for the center 

and auxiliary tank fuel boost pumps. 

Differences Between the Proposed AD 

and the Service Information 

Although Boeing Service Bulletin 

737–28A1210, Revision 1, dated May 

13, 2011; and Boeing Alert Service 

Bulletins 737–28A1227, Revision 1, 

dated July 18, 2011; and 737–28A1228, 

Original Issue, dated August 2, 2010; 

specify that certain operators may 

contact the manufacturer for 

modification instructions, this proposed 

AD would require those operators to do 

the modification using a method 

approved by the FAA. 

We received a copy of Boeing 

Information Notice 737–28A1216 IN 01, 

dated March 25, 2011; and Boeing 

Information Notice 737–28A1228 IN 01, 

dated March 25, 2011, which describe 

an issue pertaining to installation of the 

J2802 box on airplanes with airstairs. 

When the J2802 box is installed in 

accordance with Boeing Alert Service 

Bulletin 737–28A1216, Original Issue, 

dated July 29, 2010; or 737–28A1228, 

Original Issue, dated August 2, 2010; the 

forward face of the box will interfere 

with the airstairs and the airstairs 

support structure. Boeing is currently 

designing a new J2802 box for airplanes 

with airstairs. Installation of the 

automatic shutoff system required by 

paragraph (g) of this AD only applies to 

the affected airplanes without airstairs. 

In addition, installation of the ‘uncommanded ON’ protection system 

required by paragraph (m) of this AD 

only applies to the affected airplanes 

without airstairs. We may consider 

further rulemaking for installations of 

the automatic shutoff system and the 

‘un-commanded ON’ protection system 

on those affected airplanes with 

airstairs. Installation of a placard 

required by paragraph (i) of this AD 

applies to all affected airplanes 

regardless of airstairs. Once the 

automatic shutoff system is installed on 

any airplanes in an operator’s fleet, a 

placard must be installed on all affected 

airplanes not equipped with an 

automatic shutoff system. 

Although Boeing Alert Service 

Bulletins 737–28A1216, Original Issue, 

dated July 29, 2010; and 737–28A1228, 

Original Issue, dated August 2, 2010; 

refer to Boeing Alert Service Bulletin 

737–28A1210, Original Issue, dated 

August 2, 2010, as a concurrent 

requirement, this AD refers to Boeing 

Service Bulletin 737–28A1210, Revision 

1, dated May 13, 2011. Since the P5–2 

fuel system module assembly part 

numbers and the associated airplane 

group numbers, as shown in the figures 

of Boeing Alert Service Bulletin 737– 

28A1210, Original Issue, dated August 

2, 2010, may be incorrect for certain 

airplanes due to interchangeability of 

certain part numbers, this AD requires 

Revision 1 of that service bulletin. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 701 airplanes of U.S. registry. 

Of those 701 airplanes, 554 airplanes are 

without airstairs. 

We estimate the following costs to 

comply with this proposed AD:

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. 

For the reasons discussed above, 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, 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.

certain operator maintenance documents to 

include new inspections. Compliance with 

these inspections is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired in 

the areas addressed by these inspections, the 

operator may not be able to accomplish the 

inspections described in the revisions. In this 

situation, to comply with 14 CFR 91.403(c), 

the operator must request approval for an 

alternative method of compliance according 

to paragraph (t) of this AD. The request 

should include a description of changes to 

the required inspections that will ensure the 

continued operational safety of the airplane. 

Subject 

(d) Joint Aircraft System Component 

(JASC)/Air Transport Association (ATA) of 

America Code 28, Fuel. 

Unsafe Condition 

(e) This AD was prompted by fuel system 

reviews conducted by the manufacturer. We 

are issuing this AD to prevent operation of 

the center and auxiliary tank fuel boost 

pumps with continuous low pressure, which 

could lead to friction sparks or overheating 

in the fuel pump inlet that could create a 

potential ignition source inside the center 

and auxiliary fuel tanks. These conditions, in 

combination with flammable fuel vapors, 

could result in a fuel tank explosion and 

consequent loss of the airplane. 

Compliance 

(f) Comply with this AD within the 

compliance times specified, unless already 

done. 

Installation of Automatic Shutoff System for 

the Center and Auxiliary Tank Fuel Boost 

Pumps 

(g) Within 36 months after the effective 

date of this AD, do the actions required by 

paragraph (g)(1), (g)(2), or (g)(3) of this AD, 

as applicable. If a placard has been 

previously installed on an airplane, in 

accordance with the requirements of 

paragraph (i) of this AD, the placard may be 

removed from the flight deck of only that 

airplane after the automatic shutoff system 

has been installed, as specified in paragraph 

(g)(1), (g)(2), or (g)(3) of this AD, as 

applicable. Installing automatic shutoff 

systems on all airplanes in an operator’s fleet, 

in accordance with this paragraph, 

terminates the placard installation required 

by paragraph (i) of this AD, for all airplanes 

in an operator’s fleet.
