3.      Partners' Capital

The Partnership  Agreement (the Agreement) stipulates different methods by which
revenue,  income  and  loss  from  operations  and  gain or loss on the  sale of
aircraft are to be allocated  to the general  partner and the limited  partners.
Such  allocations are made using income or loss  calculated  under GAAP for book
purposes, which varies from income or loss calculated for tax purposes.

Cash  available  for  distributions,  including  the  proceeds  from the sale of
aircraft,  is  distributed  10% to the  general  partner  and 90% to the limited
partners.

                                       7


The different methods of allocating items of income, loss and cash available for
distribution  combined with the calculation of items of income and loss for book
and  tax  purposes  result  in  book  basis  capital   accounts  that  may  vary
significantly  from tax basis capital  accounts.  The ultimate  liquidation  and
distribution  of remaining cash will be based on the tax basis capital  accounts
following liquidation, in accordance with the Agreement.


                                       8


Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

At March 31, 1999,  Polaris Aircraft Income Fund III (the  Partnership)  owned a
portfolio of 10 used McDonnell  Douglas  DC-9-30  aircraft leased to Trans World
Airlines, Inc. (TWA) out of its original portfolio of 38 aircraft.


Partnership Operations

The  Partnership  reported  net  income  of  $1,459,985,  or $2.43  per  limited
partnership  unit,  for the three  months  ended March 31, 1999  compared to net
income of $1,139,825, or $1.64 per unit, for the same period in 1998.

The  increase  in net  income is due to  decreases  in  depreciation,  interest,
operating and administrative expenses, partially offset by decreases in interest
and other income, as discussed below.

The decrease in  depreciation  expense is the result of several  aircraft having
been fully depreciated down to their estimated salvage values during 1998.

Interest  expense  decreased  during the three months  ended March 31, 1999,  as
compared to the same period in 1998, due to the  continuing  payments being made
on the TWA hushkit notes payable.

Operating  expenses  decreased  during the three months ended March 31, 1999, as
compared to the same period in 1998, due to legal expenses  incurred  during the
first quarter of 1998, related to the sale of aircraft to Triton.

Administration  and other expenses decreased during the three months ended March
31, 1999, as compared to the same period in 1998, primarily due to a decrease in
printing and postage costs resulting from several  additional  investor mailings
required in the first quarter of 1998.

Interest income  decreased  during the first quarter of 1999, as compared to the
same period in 1998,  primarily  due to a decrease in the cash reserves over the
same periods.

Payments totaling $89,534 were received,  and recognized as other income, during
the  first  quarter  of 1998,  from the sale of  parts  from  nine  disassembled
aircraft. There were no such sales in 1999.

The increase in the deferred income balance at March 31, 1999 is attributable to
differences  between the  payments due and the rental  income  earned on the TWA
leases for the 10 aircraft  currently  on lease to TWA.  For income  recognition
purposes, the Partnership recognizes rental income over the life of the lease in
equal monthly amounts.  As a result, the difference between rental income earned
and the  rental  payments  due is  recognized  as  deferred  income.  The rental
payments due from TWA during the three months ended March 31, 1999  exceeded the
rental  income  earned on the TWA leases,  causing an  increase in the  deferred
income balance.


Liquidity and Cash Distributions

Liquidity - The  Partnership  received all lease  payments from its sole lessee,
TWA, except for the March 1999 lease payment.  On April 2, 1999, the Partnership
received  its $850,000  rental  payment from TWA that was due on March 27, 1999.
This amount was included in rent and other  receivables  on the balance sheet at
March 31, 1999.

                                       9



Polaris Investment Management  Corporation,  the general partner, has determined
that the Partnership  maintain cash reserves as a prudent measure to ensure that
the Partnership has available funds in the event that the aircraft  presently on
lease to TWA require remarketing and for other contingencies, including expenses
of the Partnership. The Partnership's cash reserves will be monitored and may be
revised  from  time to time as  further  information  becomes  available  in the
future.

Cash  Distributions - Cash  distributions  to limited  partners during the three
months  ended  March 31,  1999 and 1998 were  $2,299,816,  or $4.60 per  limited
partnership unit, and $14,798,816, or $29.60 per unit, respectively.  The timing
and amount of future cash distributions are not yet known and will depend on the
Partnership's  future cash requirements  (including expenses of the Partnership)
and need to retain  cash  reserves  as  previously  discussed  in the  Liquidity
section; and the receipt of rental payments from TWA.


Impact of the Year 2000 Issue

The inability of business  processes to continue to function correctly after the
beginning of the Year 2000 could have serious  adverse  effects on companies and
entities throughout the world. As discussed in prior filings with the Securities
and Exchange  Commission,  the General  Partner has engaged GE Capital  Aviation
Services,   Inc.  ("GECAS")  to  provide  certain  management  services  to  the
Partnership.  Both the General Partner and GECAS are  wholly-owned  subsidiaries
(either direct or indirect) of General  Electric Capital  Corporation  ("GECC").
All of the Partnership's operational functions are handled either by the General
Partner  and  GECAS  or  by  third   parties  (as  discussed  in  the  following
paragraphs), and the Partnership has no information systems of its own.

GECC and GECAS have  undertaken a global  effort to identify  and mitigate  Year
2000 issues in their information systems, products and services,  facilities and
suppliers  as well as to assess the extent to which Year 2000 issues will impact
their  customers.   Each  business  has  a  Year  2000  leader  who  oversees  a
multi-functional  remediation  project team responsible for applying a Six Sigma
quality approach in four phases:  (1)  define/measure  -- identify and inventory
possible  sources of Year 2000 issues;  (2) analyze -- determine  the nature and
extent of Year 2000 issues and develop  project  plans to address  those issues;
(3) improve -- execute project plans and perform a majority of the testing;  and
(4) control -- complete  testing,  continue  monitoring  readiness  and complete
necessary  contingency  plans. The progress of this program is monitored at each
business, and company-wide reviews with senior management are conducted monthly.
The first three  phases of the program  have been  completed  for a  substantial
majority of  mission-critical  activities.  Management  plans to have nearly all
significant  information  systems,  products and services and facilities through
the control phase of the program by mid-1999.

As noted elsewhere,  the Partnership has ten aircraft remaining in its portfolio
at this time.  All of these  remaining  aircraft  are on lease with Trans  World
Airlines,  Inc. ("TWA"). TWA has advised GECAS that it has adopted procedures to
identify  and  address  Year 2000  issues  and that it has  developed  a plan to
implement  required  changes in its equipment,  operations  and systems.  To the
extent,  however,  that TWA suffers any material  disruption of its business and
operations  due to Year 2000 failure of equipment or information  systems,  such
disruption  would  likely have a material  adverse  effect on the  Partnership's
operations and financial condition.

Aside  from  maintenance  and  other  matters  relating  to  the   Partnership's
aircraft-related  assets discussed above, the principal  third-party  vendors to
the  Partnership  are those  providing  the  Partnership  with  services such as
accounting,  auditing, banking and investor services. GECAS intends to apply the
same standards in determining the Year 2000  capabilities  of the  Partnership's
third-party  vendors as GECAS will apply  with  respect to its  outside  vendors
pursuant to its internal Year 2000 program.

                                       10



The  scope  of the  global  Year  2000  effort  encompasses  many  thousands  of
applications  and computer  programs;  products  and  services;  facilities  and
facilities-related  equipment;  suppliers; and, customers. The Partnership, like
all  business  operations,  is also  dependent  on the Year  2000  readiness  of
infrastructure   suppliers   in   areas   such   as   utility,   communications,
transportation  and other services.  In this  environment,  there will likely be
instances of failure that could cause disruptions in business  processes or that
could affect  customers'  ability to repay  amounts owed to the  Partnership  or
vendors' ability to provide services  without  interruption.  The likelihood and
effects of failures in infrastructure systems, over which the Partnership has no
control,  cannot  be  estimated.  However,  aside  from the  impact  of any such
possible failures or the possibility of a disruption of TWA's business caused by
Year 2000  failures,  the General  Partner does not believe that  occurrences of
Year  2000  failures  will  have a  material  adverse  effect  on the  financial
position, results of operations or liquidity of the Partnership.

To date, the Partnership has not incurred any Year 2000 expenditures nor does it
expect  to incur any  material  costs in the  future.  However,  the  activities
involved in the Year 2000 effort  necessarily  involve estimates and projections
of activities and resources that will be required in the future. These estimates
and projections could change as work progresses.
