.... Def Stan 00-970? It's out of date and maintained by people who wouldn't recognise airworthiness if it walked up and slapped them in the face!
Never a truer word.
00-970 used to mandated in every aircraft related contract. In 1997 I had my first experience of a new boss who'd been on the half day seminar that told him it WASN'T mandated and he, a physiologist (someone who makes lemonade), could make up or waive design and airworthiness requirements as he saw fit. RIP those who died as a result. After that, who would want to work in the section charged with maintaining it? A crap job.
00-970 is the REQUIREMENTS, but MoD has a -05 series of PROCEDURAL Def Stans telling you how to implement the regs. They too used to be mandated in every aircraft / equipment contract. The most important one, 05-125/2, has been cancelled without replacement. (It covers the procedures that result in a valid Safety Case. Only an idiot doesn't retain and secretly use the two books, especially Book 2). The other main one, 05-123, is fine as far as it goes, but like most such publications assumes a degree of training and proven competence in the target audience. However, this hasn't been policy since 1990. Today, so few have any practical experience, whereas 30 years ago a third year apprentice was expected to understand every word and could relate it to work he'd performed.
Remember "ARM"? Availability, Reliability and Maintainability. We no longer have named individuals responsible for this.
All of which makes bridgets boy's challenge an interesting one! I'd narrow it down to UK-built but with no French Connection (which excludes Lynx, Puma - the French simply don't "do" configuration control) and introduced and matured before the above policy changed aircraft design, ARM and safety for ever. Sea King anyone? She doesn't necessarily comply with 00-970, but in important areas Westland's own procedures are more robust (with the company content to ignore idiotic instructions from MoD!) and, ultimately, their Safety Case procedures document has stood the test of time. (The MAA would do well to get a copy and read it).
