NTSB Safety Recommendations A-10-088 through -95

************************************************************

Therefore, the National Transportation Safety Board makes 
the following recommendations to the European Aviation 
Safety Agency: 
Modify the small and medium flocking bird certification test 
standard in Joint Aviation Regulations-Engines to require 
that the test be conducted using the lowest expected fan 
speed, instead of 100-percent fan speed, for the minimum 
climb rate. (A-10-88) 

During the bird-ingestion rulemaking database (BRDB) working 
group's reevaluation of the current engine bird-ingestion 
certification regulations, specifically reevaluate the Joint 
Aviation Regulations-Engines (JAR-E) large flocking bird 
certification test standards to determine whether they 
should 1) apply to engines with an inlet area of less than 
3,875 square inches and 2) include a requirement for engine 
core ingestion. If the BRDB working group's reevaluation 
determines that such requirements are needed, incorporate 
them into JAR-E and require that newly certificated engines 
be designed and tested to these requirements. (A-10-89)

Require manufacturers of turbine-powered aircraft to develop 
a checklist and procedure for a dual-engine failure 
occurring at a low altitude. (A-10-90) 

Require applicants for aircraft certification to demonstrate 
that their ditching parameters can be attained without 
engine power by pilots without the use of exceptional skill 
or strength. (A-10-91) 

Require Airbus to redesign the frame 65 vertical beam on 
A318, A319, A320, and A321 series airplanes to lessen the 
likelihood that it will intrude into the cabin during a 
ditching or gear-up landing and Airbus operators to 
incorporate these changes on their airplanes. (A-10-92) 

Require, on all new and in-service transport-category 
airplanes, that cabin safety equipment be stowed in 
locations that ensure that life rafts and/or slide/rafts 
remain accessible and that sufficient capacity is available 
for all occupants after a ditching. (A-10-93) 

Require quick-release girts and handholds on all evacuation 
slides and ramp/slide combinations. (A-10-94) 

Require modifications to life vest stowage compartments or 
stowage compartment locations to improve the ability of 
passengers to retrieve life vests for all occupants. (A-10-
95)
