Within 6 Months

March 30, 2007: Mode-S Elementary (ELS) and Enhanced (EHS) Surveillance

June 21, 2007: Part 125 LODA Waivers
Under new FAA Notice 8000.345, by June 21, each holder of a letter of deviation authority (LODA), applicable to operators of corporate jetliners (such as the ACJ and BBJ) requesting a waiver from Part 125 to operate under Part 91, must submit a “written plan” that outlines how it will comply with the requirements of each section of Part 125 and comply with the requirements no later than March 31, 2008.

Within 12 Months

Oct. 31, 2007: Oil-spill Plan Implementation
Oct. 31, 2007, is the new deadline by which FBOs and other fueling providers must implement their amended oil-spill prevention and control plan approved
by the Environmental Protection Agency.

Feb. 15, 2008: Part 135 ETOPS Requirements
The FAA issued a final rule on multiengine turbine airplane extended operations (ETOPS) that now applies to Part 135 on-demand air-taxi operators. The rule requires that airplane systems be able to support lengthy diversions in remote and sometimes harsh environments. The rule also carries special maintenance requirements (except for aircraft with three or more engines), equipment mandates and specific ETOPS crew training (Part 135.364 and Part 135 Appendix G).

Beyond 12 Months

Dec. 16, 2008: Fuel Tank Safety
A rule (Far 121.370) that requires FAR Part 121 air carriers to change the way airplane fuel tanks are inspected and maintained has a compliance deadline of Dec. 16, 2008.

Feb. 1, 2009: Emergency Locator Transmitters
Satellite processing of distress signals from 121.5- and 243-MHz ELTs is scheduled
to end on Feb. 1, 2009. After this date, operators should switch to 406-MHz ELTs, which will be monitored by satellites. Some operations already require 406-MHz ELTs.

March 30, 2009: Mode-S EHS Extension
Eurocontrol has introduced further flexibility for mode-S enhanced surveillance (EHS) compliance by granting a two-year extension to March 30, 2009, to upgrade the remaining aircraft from mode-S elementary surveillance (ELS) to EHS standards. Exemptions will be granted on a case-by-case basis, and only for aircraft that are not EHS capable. (

Nov. 14, 2009: FAA Designee Program

On Nov. 14, 2005, the FAA implemented its organization delegation authorization program to replace the current designee program. Current designated airworthiness inspectors, maintenance inspectors, engineers and other designees have until Nov. 14, 2009, to transition their credentials to qualify for the new designation (FAR Parts 21, 121, 135, 145 and 183).
