My interpretation: So, perform an inspection unless you have already performed the 2001 AD mandated inspection... Once you perform the 2001 AD inspection you have ten years/2500 flight hours until you need to inspect again.
This AD doesn't appear to be nearly as dire as many predicted, unless of course you have damage like the EAA found. Kudos to them for identifying the failure before a risk to flight safety was realized.

FAA estimates the following costs to comply with this AD:
Inspections* 25 work-hours X $85 per hour = $2,125 $25 $2,150 $38,700
Reporting 1 work-hour X $85 per hour = $85 $0 $85 $1,530
*Estimates are provided for the eddy current bolt hole inspections of the most inboard fastener
only.

(g) Inspection
Before further flight: Perform inspections to detect cracking and corrosion by
doing the actions specified in either paragraph (g)(1) or (2) of this AD. No action is
required by this AD if all wing terminal fittings have been inspected in accordance with
paragraph (b)(1) of AD 2001-22-06, Amendment 39-12485 (66 FR 54111, October 26,
2001), and, as of the effective date of this AD, no more than 10 years or 2,500 flight
hours have accumulated since that inspection.

(1) Separate all 8 wing terminal-to-spar chord joints (wings off) and perform a
magnetic particle inspection of the steel terminal fittings and an eddy current inspection
of the 8 inboard holes in the end of the spar chord, in accordance with procedures
approved by the Manager, West Certification Branch, FAA.
(2) On the left and right lower forward terminal fitting-to-spar chord joint
assemblies, remove the most inboard fastener common to the spar cord and the terminal
fitting, and do an eddy current bolt hole inspection on the steel terminal fittings and on
the aluminum spar chord in accordance with procedures approved by the Manager, West
Certification Branch, FAA.
