Questions 

For Lenders 

1. Are small- or medium-sized 

manufacturers a part of your ordinary 

portfolio of loans? If not, why not? 

2. What are the biggest impediments 

to a small- or medium-sized 

manufacturer receiving a loan from your 

lending institution? Are there types of 

manufacturers (company size, industry 

etc.) that you would be more hesitant to 

loan to than others? 

3. Would a new loan guarantee 

program make you more likely to lend 

to manufacturers especially small- or 

medium-sized manufacturers? If so, why 

and what increase in loan volume to 

these companies would you estimate 

would occur? 

4. If EDA established a new Federal 

loan guarantee program that offered loan 

guarantees for targeted loans for smallor medium-sized manufacturers to 

support the use or production of 

innovative technology (as defined 

above) how much of a guarantee would 

your lending institution need in order to 

be willing to offer loans for such 

purposes? Besides the level of the 

guarantee, are there any other 

requirements that you would have of the 

guarantee program in order to offer such 

loans? 

5. What would your lending 

institution require for a borrower to 

demonstrate that a market exists for an 

innovative technology product? 

6. With the support of a loan 

guarantee program, what size loans 

would you anticipate making to 

manufacturers who meet the definition 

of small- or medium-sized and would 

you use the loan proceeds to support the 

use or production of innovative 

technologies? 

7. If such a Federal program were 

created, what additional requirements 

would you require from the 

manufacturers, if any, to support such a 

loan? 

8. Have you ever participated in a 

loan guarantee program (for example, 

any guarantee program provided by 

SBA? If not, why not? If so, would you 

recommend this process to others? What 

was your experience with loan 

guarantee programs (including SBA loan 

guarantee programs)? 

For Manufacturers 

9. What is the largest sized 

manufacturer that you would consider 

calling a medium-sized manufacturer? 

10. Is access to capital an impediment 

for your development as a small- or 

medium-sized manufacturer? If so, why 

(specifically) and what is the size of 

your firm? 

11. If accessing capital is an 

impediment, is securing a loan via a 

new Federal loan guarantee program to 

support the use or production of 

innovative technologies a strategy that 

you would pursue in order to access 

capital? If not, why not? 

12. If you would pursue a loan, what 

size loan would be necessary to support 

your development needs? 

13. Given that the purpose of this 

program would be to support innovation 

by re-equipping, expanding or 

establishing a manufacturing facility in 

the U.S., what types of activities and 

outcomes would you use the loan to 

support? 

14. Have you ever used a loan 

guarantee program (for example, any 

guarantee program provided by the 

SBA)? If not, why not? If so, would you 

recommend this process to others? What 

was your experience with loan 

guarantee programs (including SBA loan 

guarantee programs)? 

General 

15. Are there any additional 

comments that you would like to offer 

about the proposal to establish a loan 

guarantee program that targets the use or 

production of innovative technologies 

for manufacturing?

Airworthiness Directives; the Boeing 

Company Airplanes 

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 747–200B, 

747–200F, 747–300, 747SP, 747–400, 

and 747–400F series airplanes equipped 

with Rolls-Royce RB211–524 engines; 

and certain Model 767–300 series 

airplanes equipped with Rolls-Royce 

RB211–524 engines. This proposed AD 

was prompted by multiple reports of 

uncommanded thrust reverser unlock 

events. This proposed AD would require 

replacing certain relays and relay 

sockets, and doing wiring changes. For 

certain airplanes, this proposed AD 

would also require installing new relay 

panels, and removing and installing 

certain components. Additionally, this 

proposed AD would require, for certain 

airplanes, accomplishing concurrent 

actions, which include installing an 

additional locking system on the thrust 

reversers, installing an additional 

locking gearbox on each engine and 

modifying system wiring for in-flight 

fault indications of the thrust reverser 

system, and installing a second locking 

gearbox system on the thrust reversers. 

We are proposing this AD to prevent an 

uncommanded thrust reverser 

deployment during takeoff or in-flight 

resulting in decreased airplane control 

and performance, possible runway 

excursions, and failure to climb. 

DATES: We must receive comments on 

this proposed AD by June 3, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

about this proposed AD. 

Discussion 

We have received multiple reports of 

uncommanded thrust reverser unlock 

events. In three of these events, all three 

thrust reverser locks had disengaged. 

One report stated that during takeoff roll 

on a Rolls-Royce RB211–524-powered 

Model 747–400 airplane, the flightcrew 

received the ENG 4 REV LIMTD EICAS 

status message and the ENG 4 

REVERSER advisory and status 

messages. During climb, the cabin crew 

saw sparks from the exhaust of the 

number 4 engine. The event was found 

to be caused by a failure of the o-rings 

in the air motor switcher or shutoff 

solenoid valves because of overheating. 

This let the air motor shutoff valve 

open, which released the air motor 

brake. Releasing the air motor brake in 

the ground mode energized the number 

2 and number 3 thrust reverser gear box 

unlock solenoids, thereby unlocking the 

number 2 and number 3 gear boxes. The 

thrust reverser system on the RollsRoyce RB211-powered Model 767 

airplane is similar to that on the Model 

747–400 airplane, and the Model 767 

airplane thrust reverser system is likely 

to be susceptible to the same failure 

mode. This condition, if not corrected, 

could result an uncommanded thrust 

reverser deployment during takeoff or 

in-flight resulting in decreased airplane 

control and performance, possible 

runway excursions, and failure to climb.

Other Relevant Rulemaking 

AD 2000–01–05, Amendment 39– 

11502 (65 FR 1051, January 7, 2000), 

which applies to certain Boeing Model 

747–100B, –200, –300, and 747SP series 

airplanes equipped with Rolls-Royce 

RB211–524B2, C2, and D4 engines, 

requires repetitive inspections and tests 

of the thrust reverser control and 

indication system on each engine, and 

corrective actions if necessary; 

installation of a terminating 

modification; and repetitive operational 

checks of that installation, and repair if 

necessary. AD 2000–01–05 refers to

the appropriate source of service 

information for accomplishing the 

required terminating action. 

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. 

The phrase ‘‘related investigative 

actions’’ might be used in this proposed 

AD. ‘‘Related investigative actions’’ are 

follow-on actions that: (1) Are related to 

the primary actions, and (2) are actions 

that further investigate the nature of any 

condition found. Related investigative 

actions in an AD could include, for 

example, inspections. 

In addition, the phrase ‘‘corrective 

actions’’ might be used in this proposed 

AD. ‘‘Corrective actions’’ are actions 

that correct or address any condition 

found. Corrective actions in an AD 

could include, for example, repairs.

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.

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B16 

(CL–601–3A, CL–601–3R, and CL–604 

Variants) airplanes. This proposed AD 

was prompted by reports of airspeed 

mismatch between the pilot and copilot’s airspeed indicators, which 

occurred during or after heavy rain. This 

proposed AD would require, for certain 

airplanes, inspecting for drain bottles 

having certain part numbers, and 

replacing affected drain bottles. This 

proposed AD would require, for certain 

other airplanes, replacing drain bottles. 

We are proposing this AD to prevent 

pitot static tubing from becoming 

blocked by water, which if not 

corrected, could lead to erroneous 

airspeed and altitude indications, and 

consequent loss of control of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by June 3, 2013. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to

Discussion 

Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canadian 

Airworthiness Directive CF–2012–30, 

dated December 7, 2012 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

A number of reports were received from the 

operators indicating airspeed mismatch 

between the pilot and co-pilot’s airspeed 

indicators. The erroneous indication 

occurred during or after heavy rain. Further 

investigation revealed that during heavy 

precipitation, the pitot static tubing may 

become partially or completely blocked by 

the water which didn’t enter the drain 

bottle(s). This condition, if not corrected, 

may result in erroneous airspeed and altitude 

indications [and consequent loss of control of 

the airplane]. 

This [Canadian] AD mandates [for certain 

airplanes] the replacement of the drain 

bottles to improve drainage of the pitot-static 

tubing [and, for certain other airplanes, an 

inspection for, and replacement of, certain 

drain bottles]. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

Bombardier, Inc. has issued the 

following service bulletins. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

• Bombardier Service Bulletin 601– 

0617, Revision 03, dated December 20, 

2012. 

• Bombardier Service Bulletin 604– 

34–065, Revision 02, dated December 

20, 2012. 

• Bombardier Service Bulletin 605– 

34–027, Revision 02, dated December 

20, 2012. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 77 products of U.S. registry. 

We also estimate that it would take 

about 5 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost up to $2,939 per
