Notwithstanding the actual wording, I would hold that this does in fact
"match" the classic interpretation of "annual maintenance" vs
"routine/regular/monthly maintenance". Specifically, my interpretation of
what sort of maintenance (in broad terms, not in detail) is covered by
[R/R/M] vs [A] is as follows:

[R/R/M]
Any maintenance or repairs that can be performed while under way, with
parts, materials, and tools that are on hand, and which does not render any
area of the ship unusable or uninhabitable for the duration of a jump. This
(obviously) excludes work on the Jump Drive or hull, (less obviously) any
work that would require inspection/re-certification of the system in
question, and may exclude _some_ (but not necessarily all) work on life
support, the maneuver drives, weapons (if mounted) and
control/computers/sensors - principally work that must be done from outside
the hull, or which completely disables essential systems for the duration
of the repairs/maintenance.

The DGP/MegaTraveller Task Profile would be

To Perform Routine/Regular/Monthly maintenance:
Routine, [Engineering or Mechanical, INT or DEX], 3 hours
Referee: Any mishap has the following cumulative effects:
  1. For the next performance of this task:
     a. increases the difficulty by one level
     b. increases the time increment by one hour.
  2. Incurs a -DM (referee's discretion on value) on most Engineering or
     Mechanical tasks until this task is performed succesfully.
  A Success at this task causes the next performance to reset to the above
  base values.
  Each additional crew with chosen skill involved gives DM +1
  The total time spent on this task is spread out over the entire jump.

[A]
Any maintenance or repairs that cannot be performed while under way. This
specifically includes hull and jump drive work (which must be done at an A
or B port), or any work requiring parts, materials, or tools that cannot
(for technical/logistical or legal reasons) be kept on hand aboard ship
(which may not be done at D or E ports). It also includes any work that
would require inspection/re-certification of the system in question (may
not be done at D or E port, can be done at C ports only on worlds of TL C+
and POP 8+), and also includes work on essential systems that would require
a complete shutdown of the system in question. It also includes "routine"
updating of navigation data/"rutters"/"sailing directions"/etc (must be
done at A or B port). Often, the reason for the 'canonical' two weeks is to
allow for inspection/re-certification.

The DGP/MegaTraveller Task Profile would be

To perform annual maintenance
Difficult, [*Special, **Special], 1 day
Referee: DM -1 if at port C-. Any mishap makes the ship unspaceworthy, and
the task must be immediately tried again at difficulty FORMIDABLE. *"Skill"
to be used is average of Engineering+Mechanical+Electronic;
**"Characteristic" is average of INT+DEX. Each additional crew involved
with any of listed skills gives DM +1; task may be avoided (automatic
success) at A or B ports by hiring out to starport specialists at Cr1,000
for lead engineer, +Cr500 for each assistant; time required if hired out
will be 10 days - (1 day per assistant hired) (that is, lead engineer
alone, 10 days; lead engineer + 1 assistant, 9 days; lead engineer + 2
assistants, 8 days; etc.). (Cost of hiring out is in addition to normal
maintenance cost allocations or port fees.)
