This search engine is rather simplistic. It searches
sequentially through the NTSB's. But it works ;-)
All input fields are case insensitive, so you can enter upper or lower
case letters.
In the search, the entries within one field (separated by semicolon)
are 'or'd, and different fields are 'and'd. This means that for
instance if you specify 'NY;FL' in the State field, you will get all
entries for accidents that happened either in New York, or in Florida.
If you specify 'NY' in the State field and 'Cessna' in the aircraft
make/model field, you will get only entries involving accidents of
Cessnas in New York state. If you don't know the exact spelling of,
for instance an engine designation, use wildcard notation (see Unix style
regular expression). For instance IO.*360 searches for 'IO'
followed by zero or more characters of any sort, followed by '360'.
This will find IO360, IO-360, and IO 360 (with a space).
Numerical fields can be searched with relative numerical
expressions:
< (field is less than specified value)
> (field is greater than specified value)
.. (the range operator, field is between lower and upper limit. This
operator has to be preceded and followed by a blank).
For instance if you specify 100 .. 200, all briefs with a value in
that field between 100 and 200 will be returned. Specifying 100..200
will not work. You can specify multiple conditions in these
fields too (e.g. < 100 ; > 900)
Some fields with checkboxes have a selection called "match all
selections". If this is checked, only briefs that contain all the
selected items in the block for with it is checked are returned. If
it is not checked, briefs that contain at least one of the items are
returned.
In the Narrative and Accident Cause field, each line is treated as a
phrase and the database is searched for the exact sequence of words in
each line.
Since the search is sequential, it may take a while before it returns.
When possible, it is advisable to limit the search
by using a start and end date.
IMPORTANT: Fill in only as much information as necessary to
find what you are looking for. If you fill in too many fields, they
may contradict each other and you will find nothing. Start with one
field, then narrow the search by progressively filling in more
constraints.
