Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; correction. 

SUMMARY: The FAA is correcting an 

airworthiness directive (AD) that 

published in the Federal Register. That 

AD applies to RB211–Trent 800 series 

turbofan engines. The last comment 

response in the preamble and the first 

sentence of regulatory text paragraph 

(g)(1) are incorrect. The repetitive 

inspection interval should be 2,000 

flight cycles, not 1,000 flight cycles. 

This document corrects those errors. In 

all other respects, the original document 

remains the same. 

DATES: This final rule is effective April 

11, 2012. 

ADDRESSES: You may examine the AD 

docket on the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The address for the

liner head section for cracking, and if 

found cracked, removing the front

As published, the last comment 

response in the preamble, and the first

SUPPLEMENTARY INFORMATION: Teva 

Animal Health, Inc., 3915 South 48th 

Street Ter., St. Joseph, MO 64503, has 

informed FDA that it has transferred 

ownership of, and all rights and interest 

in, ANADA 200–136 for Tetracycline 

Hydrochloride Soluble Powder 324; 

ANADA 200–303 for Lincomycin 

Hydrochloride Soluble Powder; and 

ANADA 200–347 for Penicillin G 

Potassium, USP, all soluble powders 

administered in drinking water to Quo 

Vademus, LLC, 277 Faison West 

McGowan Rd., Kenansville, NC 28349. 

Accordingly, the Agency is amending 

the regulations in part 520 (21 CFR part

and a current format. 

In addition FDA has noticed two 

errors in § 520.1696 Penicillin oral 

dosage forms. At this time, § 520.1696a 

is being removed because no sponsor is 

listed, and an obsolete drug labeler code 

is being removed from § 520.1696d.
