. . .and
then there was. . . data.
1984, the Helicopter Association International (HAI) began to
develop a system that would facilitate the collection and collation
of empirical data on any removable airframe or engine part(s);
including service difficulties with helicopters, and timely
analysis of that data. HAI's Maintenance/Technical Committee
took the lead in this effort, which became known as the Maintenance
Malfunction Information Report (MMIR) System.
the approval of HAI's Board of Directors, including the necessary
financial backing and supported by the HAI staff, the Maintenance/Technical
Committee designed a one-page, four-copy, self-carboning MMIR
form. This "universal" form was accepted by manufacturers
for warranty claim and by the FAA in lieu of the SDR. Initially,
HAI printed and circulated 10,000 copies of this form for field
of the new form was very high, and minor modifications were
made based on user responses. The procedure was for a reporting
organization to retain one copy and submit one copy each to:
the FAA, the manufacturer, and HAI. At first, all processing
was manual; the data was extracted from the hard copies and
entered into a computer system. This was undertaken as an interim
measure, with the realization that the sheer volume of reports
would soon overwhelm any manual system.
the COTS (commercial off-the-shelf) database development program
FoxPro, HAI developed a software version of the MMIR form. The
MMIR software package uses lookup tables to access data such
as the ATA codes, part numbers, aircraft model numbers, or addresses.
The lookup tables ensure data accuracy and reward the user with
fast form completion by eliminating repetitive, redundant entries.
MMIR software has been fine tuned and improved through extended
field evaluations with operators such as Petroleum Helicopters
and Era Aviation. Thanks to their help, significant improvements
have been made to the MMIR software, including default data
fields, duplicate record function, key word search, and automatic
data filing via the Internet.
is now Web-based. The data is collected at HAI and analysis
reports are available for MMIR users. These reports provide
crucial information for trend monitoring, which has the potential
to detect incipient failures on a real-time basis, as well as
to supply justification data to extend life limits and/or overhaul
the original MMIR paper form is still in use today, the MMIR
program has evolved into a comprehensive, automated, computerized
maintenance management tool. Hundreds of users have saved time
and money by making the painless transition to the electronic
