(8) Out-of-ground effect hover 

performance determined under § 29.49 

and the maximum safe wind 

demonstrated under the ambient 

conditions for data presented. In 

addition, the maximum weight for each 

altitude and temperature condition at 

which the rotorcraft can safely hover 

out-of-ground-effect in winds of not less 

than 17 knots from all azimuths. These 

data must be clearly referenced to the 

appropriate hover charts; and

■ 22. Amend Appendix B to Part 29 in 

paragraph V(b) by removing the word 

‘‘cycle’’ and adding the word ‘‘cyclic’’ in 

its place; and by revising paragraphs 

V(a) and VII(a) to read as follows: 

Appendix B to Part 29—Airworthiness 

Criteria for Helicopter Instrument 

Flight 

* * * * * 

V. Static Lateral Directional Stability 

(a) Static directional stability must be 

positive throughout the approved ranges of 

airspeed, power, and vertical speed. In 

straight and steady sideslips up to ±10° from 

trim, directional control position must 

increase without discontinuity with the angle 

of sideslip, except for a small range of 

sideslip angles around trim. At greater angles 

up to the maximum sideslip angle 

appropriate to the type, increased directional 

control position must produce an increased 

angle of sideslip. It must be possible to 

maintain balanced flight without exceptional 

pilot skill or alertness. 

* * * * * 

VII. Stability Augmentation System (SAS) 

(a) If a SAS is used, the reliability of the 

SAS must be related to the effects of its 

failure. Any SAS failure condition that 

would prevent continued safe flight and 

landing must be extremely improbable. It 

must be shown that, for any failure condition 

of the SAS that is not shown to be extremely 

improbable—

(1) The helicopter is safely controllable 

when the failure or malfunction occurs at any 

speed or altitude within the approved IFR 

operating limitations; and 

(2) The overall flight characteristics of the 

helicopter allow for prolonged instrument 

flight without undue pilot effort. Additional 

unrelated probable failures affecting the 

control system must be considered. In 

addition—

(i) The controllability and maneuverability 

requirements in Subpart B must be met 

throughout a practical flight envelope; 

(ii) The flight control, trim, and dynamic 

stability characteristics must not be impaired 

below a level needed to allow continued safe 

flight and landing; 

(iii) For Category A helicopters, the 

dynamic stability requirements of Subpart B 

must also be met throughout a practical flight 

envelope; and 

(iv) The static longitudinal and static 

directional stability requirements of Subpart 

B must be met throughout a practical flight 

envelope.

Docket No. 07–AEA–10] 

Establishment of Class E Airspace; Oil 

City, PA 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; confirmation of 

effective date. 

SUMMARY: This action confirms the 

effective date of a direct final rule that 

establishes a Class E airspace area to 

support Area Navigation (RNAV) Global 

Positioning System (GPS) Special 

Instrument Approach Procedures (IAPs) 

that serve the Northwest Medical Center 

in Oil City, PA. 

DATES: Effective 0901 UTC, February 14, 

2008. The Director of the Federal 

Register approves this incorporation by 

reference action under Title 1, Code of 

Federal Regulations, part 51, subject to 

the annual revision of FAA Order 

7400.9 and publication of conforming 

amendments.

SUPPLEMENTARY INFORMATION: 

Confirmation of Effective Date 

The FAA published this direct final 

rule with a request for comments in the 

Federal Register on December 19, 2007 

(72 FR 71762). The FAA uses the direct 

final rulemaking procedure for a non 

controversial rule where the FAA 

believes that there will be no adverse 

public comment. This direct final rule 

advised the public that no adverse 

comments were anticipated, and that 

unless a written adverse comment, or a 

written notice of intent to submit such 

an adverse comment, were received 

within the comment period, the 

regulation would become effective on 

February 14, 2008. No adverse 

comments were received, and thus this 

notice confirms that effective date.
