MA1943B
This procurement specification covers aircraft quality self-locking nuts for wrenching (hex, spline) and anchor (plate, gang channel, shank) types of nuts made from a corrosion and heat-resistant nickel-base alloy of the type identified under the Unified Numbering System as UNS N07001. Tension height nuts having overall length of threaded portion not less than 1.2 times the nominal thread diameter have 1210 MPa minimum tensile strength at room temperature. Shear height nuts having shorter threaded portion have 1100 MPa minimum tensile strength at room temperature. Maximum test temperature of parts is 730 °C.

Measurement Uncertainty and Consumer Risk

CURRENT
AIR6553
This document addresses measurement uncertainty and consumer risk as they relate to AS8879 thread inspection. It describes the rationale, theory and methodology used to generate the technical content of the AS5870. The document describes how to calculate measurement consumer risk. It documents all of the calculation methods which industry employs today to calculate what is commonly called measurement uncertainty (Appendices A, B, C, D, E and F). These, in turn, are used to calculate measurement uncertainty ratios which are required inputs to calculate measurement consumer risk. Users of this document can apply the information described herein for the evaluation of the capability of their measurements based on the measurement consumer risk. It involves the analysis of the measurement (product) distribution and biases of both the product and measurement system distributions. It protects the consumer from the worst case distribution results.

FINAL REPORT ON COLD STARTING OF RECIPROCATING AIRCRAFT ENGINES

CURRENT
AIR13A
INTRODUCT ION Conventional internal conbustion a i r c r a f t engines require the same basic conditions for starting in cold weather as they do in warn weather. These are: (1) The engine must be cranked a t a reasonable speed. ( 2 ) A combustible mixture must be delivered t o the cylinders. (3) An ignition spark must be supplied which is capable of igniting t'ne charge a t the proper t i m e . (4) The fits and olearanoes of mating parts in the engine m u s t be such that normal Sunctions occur a t a l l temperatures. (5) The engine must receive a usable lubricant. (6) The engine must develop s u f f i c i e n t power t o overcome its own f r i c t i o n and accelerate itself t o the desired operating speed.
