IMO, couple other things I found in the revised pages (if anyone sees any misinterpretations by myself, as I have no experience in the aviation industry, let me know). IMO, there were a few references to unintended slide deployment in which the data is nice, but not to be relied on completely, which would be in BLTA's favor concerning Mini #3, IMO. Also number 4 in the below quote is interesting, that overhaul and inspection time limits can be revised after

. IMO, could mean no revision in manuals or procedures for BLTA until after they are certified and have experience in operating.

(2) Two types of inspection tasks are used in aircraft maintenance: failure-finding tasks, which identify functional failures, and failure prevention tasks, which identify potential failures. Therefore, an air carrier’s maintenance time limitations should contain a list of EES tasks, consisting of on-aircraft inspections, measurements, or tests, from which a determination is made of the item’s capability to immediately perform its intended emergency purpose. Deployment or functional testing should be included and used on a sampling basis to validate the serviceability of each item of the EES. In the Continuing Analysis and Surveillance System (CASS) process (see subparagraph 6d below) for EES, an increase of failures during deployments or functional testing will initiate a corresponding increase in the sampling rate.

(3) Scheduled deployments on the aircraft or during a combination of on-
aircraft functional tests, inspections, and test-fixture usage may be used, provided the test-fixture replicates the aircraft installation. The number of scheduled deployment checks should be included for statistical validity. Inadvertent deployments, while a source of useful information, should not be considered or used as the sole source of reliability information.

(4) The inspection and overhaul time limits for EES may be revised after an air carrier has gained service experience and has substantiating data to justify a revision. The inspection periods for EES will determine the continued service readiness for emergency use. Revisions to inspection and overhaul times should be accomplished in accordance with the manufacturer’s recommendations and the air carrier’s maintenance program, where appropriate.

All IMO of course.
