Airworthiness Directives; Fokker 

Services B.V. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Proposed rule; withdrawal. 

SUMMARY: The FAA withdraws a notice 

of proposed rulemaking (NPRM) that 

proposed a new airworthiness directive 

(AD), which applies to certain Fokker 

Services B.V. Model F.28 Mark 0070 

and 0100 airplanes. The NPRM would 

have required installing fuses in the 

maximum level (Max Level) sensor 

wiring, and revising the airplane 

maintenance program by incorporating 

critical design configuration control 

limitations. Since the NPRM was issued, 

we have received new data indicating 

that the modification proposed in the 

NPRM interfered with the normal 

operation of the Max Level shutoff 

system. Accordingly, the NPRM is 

withdrawn. 

DATES: As of March 5, 2014, the 

proposed rule, which was published in 

the Federal Register on July 31, 2013 

(78 FR 46298), is withdrawn.

docket on the Internet at http://

0629; or in person at the Docket 

Management Facility between 9 a.m. 

and 5 p.m., Monday through Friday,

contains this AD action, the NPRM (78 

FR 46298, July 31, 2013), the regulatory 

evaluation, any comments received, and 

other information. The address for the

SUPPLEMENTARY INFORMATION: 

Discussion 

We proposed to amend part 39 of the 

Federal Aviation Regulations (14 CFR 

part 39) with a notice of proposed 

rulemaking (NPRM) for a new AD for 

certain Fokker Services B.V. Model F.28 

Mark 0070 and 0100 airplanes. The 

NPRM published in the Federal 

Register on July 31, 2013 (78 FR 46298). 

The NPRM resulted from a design 

review, which revealed that, under 

certain failure conditions of the Max 

Level sensor wiring, a short circuit may 

develop that causes a hot spot on the 

wiring conduit, or puncturing of the 

wiring conduit wall in the center wing 

fuel tank. The NPRM would have 

required installing fuses in the Max 

Level sensor wiring, and revising the 

airplane maintenance program by 

incorporating critical design 

configuration control limitations. The 

proposed actions were intended to 

prevent an ignition source in the center 

wing fuel tank vapor space, which could 

result in a fuel tank explosion and 

consequent loss of the airplane. 

Actions Since NPRM (78 FR 46298, July 

31, 2013) Was Issued 

Since we issued the NPRM (78 FR 

46298, July 31, 2013), we received a 

report that after an operator installed the 

fuses in the wiring of the Max Level 

sensors of the center fuel tank, as 

specified in Fokker Service Bulletin 

SBF100–28–073, dated August 10, 2012, 

the Max Level shut-off system did not 

operate correctly. After initial refueling 

shut-off, refueling restarted, leading to 

fuel spilling onto the platform. The 

manufacturer is developing a 

modification to address the unsafe 

condition that does not interfere with 

the normal operation of the Max Level 

shutoff system. We might issue AD 

rulemaking once the manufacturer has 

issued service information that includes 

the modification. 

FAA’s Conclusions 

Upon further consideration, we have 

determined that the NPRM (78 FR 

46298, July 31, 2013) does not 

adequately address the identified unsafe 

condition. Accordingly, the NPRM is 

withdrawn. 

Withdrawal of the NPRM (78 FR 

46298, July 31, 2013) does not preclude 

the FAA from issuing another related 

action or commit the FAA to any course 

of action in the future. 

Regulatory Impact 

Since this action only withdraws an 

NPRM (78 FR 46298, July 31, 2013), it 

is neither a proposed nor a final rule 

and therefore is not covered under 

Executive Order 12866, the Regulatory 

Flexibility Act, or DOT Regulatory 

Policies and Procedures (44 FR 11034, 

February 26, 1979).

The Withdrawal 

Accordingly, we withdraw the NPRM, 

Docket No. FAA–2013–0629, Directorate 

Identifier 2012–NM–214–AD, which 

was published in the Federal Register 

on July 31, 2013 (78 FR 46298, July 31, 

2013).

Airworthiness Directives; Airbus

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for certain Airbus Model A300 B4–601, 

B4–603, and B4–605R airplanes; Model 

A300 F4–605R airplanes; Model A300 

C4–605R Variant F airplanes; and Model 

A310–204 and –304 airplanes; powered 

by General Electric (GE) CF6–80C2 

series engines. The NPRM proposed to 

require installing a shunt of the rotary 

selector (introducing an auto-relight 

function). The NPRM was prompted by 

reports of two single-engine flameout 

events during inclement weather. This 

action revises the NPRM by adding an 

additional wiring modification to a 

certain circuit breaker panel. We are 

proposing this AD to prevent a long 

engine restart sequence after a nonselection of continuous relight by the 

crew and a flameout event of both 

engines, which could result in reduced 

controllability of the airplane, especially 

at low altitude. Since these actions 

impose an additional burden over that
