following correction is needed:
PART 39--[CORRECTED]
Sec. 39.13 [Corrected]
On page 49100, in the third column in the Regulatory Information,
Table 1, ``(3) One engine has a radial drive steady bearing P/N FK76084
with fewer than 600 HSN, and the other engine has a bearing P/N FK76084
with more than 1,500 HSN,'' is corrected to read ``(3) One engine has a
radial drive steady bearing P/N LK76084 with fewer than 600 HSN, and
the other engine has a bearing P/N LK76084 with more than 1,500 HSN.''
Also, Table 1 ``(4) Both engines have a radial drive steady bearing P/N
FK76084 with 600 or more HSN,'' is corrected to read ``(4) Both engines
have a radial drive steady bearing P/N LK76084 with 600 or more HSN.''
