Airworthiness Directives; Hoffmann 

Propeller GmbH & Co. KG Propellers 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Hoffmann Propeller GmbH & Co. KG 

model HO–V 62 propellers. This 

proposed AD was prompted by the 

failure of the propeller blade lag screws. 

This proposed AD would require 

removal of the affected propeller blades 

and installation of modified propeller 

blades marked with change letter ‘‘A’’ or 

‘‘B.’’ We are proposing this AD to 

address the unsafe condition on these 

products.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2017– 

0220, dated November 10, 2017 

(referred to hereinafter as ‘‘the MCAI’’), 

to address the unsafe condition on these 

products. The MCAI states: 

In 1983, occurrences were reported of 

fatigue failure of propeller blade lag screws, 

at rotation speeds between 2950 and 3250 

revolutions per minute (RPM) in flight. 

This condition, if not detected and 

corrected, could lead to in-flight propeller 

blade detachment, possibly resulting in 

damage to the powered sailplane and/or 

injury to persons on the ground. 

To address this potential unsafe condition, 

Hoffmann issued Service Bulletin (SB) 4, 

providing the necessary instructions. 

Consequently, LBA Germany issued AD 83– 

150 (later revised), which applied only to 

HO–V 62 propellers with R/L 160T blades, 

when in combination with a Limbach L 2000 

engine, to require a limitation of continuous 

operation to 2 900 RPM, to prohibit aerobatic 

flights, calibrate the tachometer, install a 

placard, and inspection of the propeller 

blades. LBA AD 83–150/4 also required 

overhaul and replacement of the affected 

propeller blades with modified blades, either 

having 5 lag screws with 12 mm diameter, or 

6 screws, and required implementing a time 

between overhaul (TBO) of 600 flight hours 

(FH). 

Since that AD was issued, based on a stress 

analysis of lag screws on blades with 

continuous operating speed above 2 900 

RPM, it was determined that the 6-screws 

configuration or the 5 screws configuration 

with increased strength is necessary to 

ensure safe propeller operation. In addition, 

since the LBA AD applied only to a limited 

population (Limbach engine only), many 

propellers have not been modified as 

described in Hoffmann SB 4C. Consequently, 

Hoffmann issued SB E34 Revision B, to 

provide blade replacement instructions. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2018– 

0281. 

Related Service Information 

We reviewed Hoffmann Propeller 

GmbH & Co. KG Service Bulletin (SB) 

E34, Rev. B, dated September 18, 2017. 

The SB describes the instructions for the 

removal and installation of the propeller 

blades. 

FAA’s Determination 

This product has been approved by 

EASA, and is approved for operation in 

the United States. Pursuant to our 

bilateral agreement with the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all the 

relevant information provided by EASA 

and determined the unsafe condition 

previously described is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

removal of the affected propeller blades 

and installation of the modified 

propeller blades marked with change 

letter ‘‘A’’ or ‘‘B’’ on the blade. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

EASA AD 2017–0220 partially 

restates the requirements of AD 83–150, 

issued on December 21, 1984, by 

German aviation authority LuftfahrtBundesamt (LBA), which is based on 

Propellerwerk Hoffmann Rosenheim SB 

4, Revision C, dated February 20, 1984. 

EASA AD 2017–0220 also adds new 

requirements based on the issuance of 


amozie on DSK3GDR082PROD with PROPOSALS1
32220 Federal Register / Vol. 83, No. 134 / Thursday, July 12, 2018 / Proposed Rules 

Hoffmann Propeller GmbH & Co. KG SB 

E34, Rev. B dated September 18, 2017. 

In restating LBA AD 83–150, EASA 

AD 2017–0220 maintains a requirement 

to remove certain propellers from 

service within 10 flight hours after 

December 21, 1984, but not later than 31 

March 31, 1985. Service Bulletin E34 

requires a mandatory immediate 

maximum propeller rotational speed 

limitation until the permanent 

corrective action is completed, within 

50 flight hours. The EASA AD 2017– 

0220 partially restated requirements of 

SB 4. Additionally, Hoffmann Propeller 

GmbH & Co. KG SB E34 Revision B and 

SB 4 Revision C temporarily prohibit 

acrobatic flight. EASA AD 2017–0220 

also adds a new requirement for a 

mandatory maximum propeller 

rotational speed limitation within 30 

days until the propeller is replaced 

within 50 flight hours. 

This proposed AD does not require a 

propeller speed limitation but would 

require removal of the affected propeller 

blades and installation of modified 

propeller blades within 30 days of the 

effective date of this AD. 

Costs of Compliance 

We estimate that this proposed AD 

affects 50 propellers installed on 

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 

Replace Blades between overhaul ................. 3.0 work-hours × $85 per hour = $255.00 ..... $3,150.00 $3,405.00 $85,125.00 

Replace Blades at overhaul ............................ 0 work-hours × $85 per hour = $0.00 ............ 3,150.00 3,150.00 78,750.00 

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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to engines, propellers, and 

associated appliances to the Manager, 

Engine and Propeller Standards Branch, 

Policy and Innovation Division. 

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.
