guidance for use of autopilots. The intended effect of this rulemaking is to allow movement of aircraft in safer and more efficient flight patterns, resulting in operator efficiency, while smoothly incorporating related technological changes. as they currently do or pursue the proposed lower minimum use heights based on their aircraft certification. Status: Final rule effective as of April 4, 2014. 112 Federal Aviation Administration Fuel Tank and System Lightning Protection (RRR) This rulemaking would remove the requirement covering lightning ignition sources for fuel tank ignition prevention. It would also the intention to prevent catastrophic fuel tank vapor ignition due to lightning in the broader fuel system lighting protection requirements. This action is necessary because of the impracticality of controlling structural lightning ignition sources, which has resulted in a series of exemptions. This action would be as it would remove the need to comply with a specific requirement that has provided little or no safety benefits. 2 01/02/2014 09/25/2014 SB: N, IC: N, SLT: N Anticipated costs and benefits: This is a burden- relieving rulemaking project, so no significant costs are anticipated. Based on historical numbers of related exemptions and type certification applications, we estimate that we would not have to process 40 exemptions over the next 20 years.
